I'm glad Cyraxpt and RayRay13000 pointed me to this thread, GOG's forum search failed to show it when I was searching for it yesterday, or at the least did it's very best to hide it in between lots of irrelevant search results thrown about in an absolutely non-logical order, but we all know that.
Anyway, now I'm here, let's copy paste from my own superfluous thread:
Operation Flashpoint: Dragon Rising:
I'm only yet in what should be the tutorial mission, but the game makes a mess of telling you how it is played (and the manual is too brief as well for my liking) 1. you miss out on instructions if you don't stand in the right spot while the game does not clearly how you should walk, the first start I walked completely without receiving instructions just for taking the wrong route 2 . the instructions how things work are sketchy, like 'press interaction button' (the makers didn't bother to make separate tutorials for each system, so instructions are the same wether you play on XBOX or PC, 'press number key to change equipment' and due to the game creating pauses after pressing the button (for realism, you don't have your weapons switched instantly IRL I walked around for a long time with just a bandage, for failing to find my weapon under 2 and just staring at a missile I was to destroy with only on my second run finding out demo charge is 7 - the manual just says 'change equipment - number buttons.
There are a lot of buttons for lots of actions (Q Quick order menu, but if you make a choice, you have to choose Q again otherwise overrule you the choice made with new, Fire Support menu is right shift, far with WASD and your mouse today, stepping into a car you have to remember B to start the engine, etc. With my style of play of playing multiple games at once, switching games for which I'm in the mood, it's hard to remember very complicated controls, if the pauses in playing a game might be weeks or months before coming back to it while I'm playing other games.
Further frustrations are the atmosphere of the game: the language is very military-technical, Medal of Honor and Battlefield series are also guilty about it, but their controls are at least simple and the voices are lifelike. Every order from above and every shout from your comrades in OF:DR are monotone and robotic and every time the same. Plus with unclear controls, unclear goals and unusual language it's becoming a huge puzzle what to do, where and how.
Finally, the whole game is set in drab brown colours: your own, the enemy troops, vehicles, buildings, the earth, the rocks, the plants: everything is coloured in different shades of pale brown. I'm still just in the first mission, but instead of gaming giving me joy, with this game it just frustrates. And the prospect is it's probably going to be a very difficult game from what I've read (and it is even less easy to get in to than it's successor Red River, which went fine until I ran into a difficulty spike I couldn't overcome when the Chinese stepped in).
I'm going to quit the Operation Flashpoint series. There are lots of other games on my backlog, I'll probably have much more fun with.
TL;DR: the conclusion could be drawn Operation Flashpoint is far too hardcore for me.
