Zookie: There are a lot of good PC games out there but not many offer much in the way of original game play. It seems to me that there has not been a whole lot of innovations in game play since the mid to late 90’s.
All the changes we have seen since have been in AI, user interface, features, presentation, or storytelling style. But game play has stayed more or less the same. For example almost all RTS games today are a variation of Warcaft, Dune II, or Total Annihilation. Almost all RPG games are all some variation on Elders Scrolls, Might and Magic, Baldur’s Gate or Diablo. All FPS are more or less a clone of Wolfenstein 3D, Half-life, or The Battlefield 1942.
You get the idea.
So what I wanted to know is what games are out there with unique and original gameplay. Games that offer something new or at least something we have not seen over and over. I am not sure if you are asking about completely new kind of game that has nothing similar to any other game ever made, or "something new"?
For instance, the original Starcraft felt quite refreshing the way it added story telling to a RTS game, and also how it was able to combine three quite different races in one game successfully (I think WarWind 1-2 might have done the latter before Starcraft, but they are mostly unknown RTS games). Or doesn't Starcraft count because it didn't create a completely new genre?
Other RTS games you might want to check out is e.g. Genewars, but it seems to be a flawed diamond.
The original Half-life could be praised the same way, new way of integrating story telling into a standard FPS game, but again it was not a new genre. And do for example following games fit your criteria, or do you consider them also "same old same old"?
- Carmageddon
- GTA (the first one, with 2D overhead view)
- Tomb Raider
Just off the top of my head some games from late 90s which I found refreshing in some ways, even if you'd be able to name some even older game that resembles them somewhat.
Having said that, you might still have some point, because two things might have curbed game innovation a bit around 1995 and after:
- CD-ROM media was finally so common that we started seeing lots of "interactive movies" with cheesy FMV acting. I am now playing Heavy Gear 1, and frankly the "movie parts" are quite painful to watch. Fortunately rest of the game seems quite ok for a mech game.
- Arrival of 3D accelerators meant that much more brain power was used to making new 3D engines for existing games, rather than coming up with new genres.
EDIT: Now I see I apparently read your message wrong. You were not asking original game ideas during years 1995-2000 (where bulk of the GOG games come from), but that there hasn't been much innovation ever since.
I think you can look at least to indie side for newer fresh ideas. Does e.g. Minecraft count, even if it was influenced by other games?
