As you might have guessed, I like simulator games. Pretty much all of them :)

Hence, I ask your recommendations. All games that have some sort of simulation would be welcomed. I would also like to know about detective and business games, if possible :)

And since I'm bothering you again with these kind of threads, I'll draw a gog of free choice (no W2) among the posters here :)

Thanks again :)

I guess as far as business, there's always the Tycoon series (Roller-coaster, Zoo (And Jurassic Park expansion), airport, car, Railroad). Actually, about everything on this list

I can't tell you good or bad because you'd have to research and decide if you think you'd be interested. GOG has a couple of the games on here, I think Tropico and Port Royal (Might be wrong).

Detective games are quite a bit harder. Most of the time detective is looped in with some sort of puzzle game. The exceptions I know are Sherlock Holmes on PC, and the Deja Vu series on NES and PC. There's also LA Noire for modern systems/consoles, but that has as much driving and shooting as investigation.

As far as true simulation games, the only things coming to mind are Microsoft programmed simulations of airplanes and trains. Then there's racing games like Need for Speed and Project Gotham racing, but I don't know your definition of Sim.

I'm not normally someone who dabbles with simulators. However, if military sims are your thing, you can't go wrong with Operation Flashpoint Cold War Crisis (or Arma Gold Edition as it's known on this site). Although I found it to get a little too complex for my tastes, it's certainly full of awesomeness. My personal recommendation would probably be SWAT 3 (also available on here). It takes a little bit to figure out how to make it work, but once you do, it's a BLAST. I'd actually say that I prefer it to Rainbow Six or Ghost Recon.

Lately i'm quite addicted to Train simulator games. I've been lucky to own both Train Simulator 2012 and Trainz Simulator 12 at the same time (Both of these are costly, but thanks to Steam sales and great gift pile, i bought Railworks 3 for dirt cheap price and won Trainz 12).

From my experience, Trainz 12 have detailed environment and train model much more than Railworks 3. Especially the tree, vege, and cockpit view. The graphic, colour are standout and the game optimized well with my decent hardware while i have experience poor performance in Railworks 3 for several location / track.

But with Railworks 3, you'll experience much more realistic way of maneuver the train. It follow real life rules too for example UK, US and Germany have different signalling and signal warning system such as AWS, PZB, TPWS. I have yet to encounter all of this factor after spending 7 hours on Trainz 12 (vanilla version).

By playing Railworks 3, i understand why train need to stop several time in the middle of the course. Average Joe will always blame the train driver, while in reality they must follow the rule. The UI is much more user friendly, you'll know in advance your next stop. So you could time your braking really well. There's one thing that missing in Trainz which is for me is quite game breaker (since the game is sold as simulator). The train doesn't have shaky effect or feel when you went through bumpy road at high speed. You can hear the sound effect, but your train is glued to the rail.

Another game that i currently play is Ship Simulator Extremes, it's addictive too. But i have no experience boarding real ship, so i can't comment whether it's realistic or not.

Next, i'm gunning for Euro Truck Simulator 2 which will be release this March. From the preview, it's very interesting concept, realistic with nice graphic (which is rare for niche simulator title). I always have soft spot for truck.

Evil Genius is the ultimate Evil Genius simulation. Okay, probably the only one, but my point is still valid, I swear!

Hmm...I'd also recommend The Nations Gold, it looks very fantasy-ish but it actually is a pretty sophisticated village management sim.

And I used to adore Caesar III, played it all the time - I liked that one because you could build to achieve economic goals and not worry too much about the military.

UFO Aftershock is a nice take on the X-com minigenre, and is pretty sophisticated in terms of resource management and squad outfitting/command. Diplomacy's pretty darn weak, though.

As far as games NOT on GOG go, umm...

X-com? Yeah, that.

You speak my language. +1

KTC, are you thinking PC only?

*Spoiler Alert* Not all of my suggestions are serious.

Android/iOS
Game Dev Story - It's an awesome business sim in which you run a game developer.

PC
Caesar II - I prefer it over any of the other entries in the series.
Dive to the Titanic - Apparently doesn't work that well but I'd still like to check it out.
Serious Sam HD The Second Encounter - Best mass-murder sim on the market.
Cities in Motion - Transport sim.
Majesty 2 - It is subtitled "The Fantasy Kingdom Sim."
ARMA II - Military sim. There are multiple expansions. Best in multiplayer as the AI is horrible.

My first choice: Game Dev Story

Tetris : excellent mason simulator.

The Tex Murphy series.
x1000000

Hacker Evolution seems to be pretty well-received. Haven't played it myself, though.

Also Gran Turismo, IL-2 1946 and Operation Flashpoint (preferably with the FDF mod).
E: Sorry, the FinnWars mod was another thing altogether.

If you're open to non-pc games, Phoenix Wright: Ace Attorney is a fantastic detective type game on the iOS platform. While you play as a defence attorney, you do your own detective work in order to uncover what really happened and prove your clients' innocence.

I think Football Manager might fit. Give it a shot.
When I was a kid I used to play a lot of Ocean Trader. Was fun!

Farming Simulator 2011

Agricultural Simulator 2011

Here is a brief comparision
http://forums.steampowered.com/forums/showthread.php?t=1769943

I played Farming simulator only so I can't compare two.

I also second the (Railworks 3) Train Simulator 2012 suggestion, it's great really.

X3: Terran Conflict is a great space-sim with an elaborate economics part: you can set up your own factories, automate traders etc. If you like space-sims, have a lot of time on your hands and don't mind a rather steep learning curve, you might want to check it out. I would recommend checking the official forums (on www.egosoft.com) for mods and scripts though, there is a lot of stuff that improves on many game aspects, reduces micromanagement and makes it much more enjoyable overall. There are also mods that add lots of stuff, complete overhauls etc. X3 is my second most modded game, right after the Elder Scrolls titles ;)

From what I've read, the most recent expansion Albion Prelude is not worth it so far, because of some removed quests, performance problems and because of the incompatibility with many mods/scripts (most of the additions are reworked community mods/scripts which are available for TC).

Reeperbahn Simulator

Don't know the Reeperbahn? You need to come to Hamburg-Germany ;)

I recommend SimCity 4.even though is not like SC2K,it's a strong title for the series and one of my favourite games.
