I think this is a pretty accurate list. Although some might be in the wrong spot, all the titles are there. I really think Spore should be #1. I don't think many people understand the impact this game is going to have. I really think this game will change PC gaming, it will bring in a whole new audience and change the way we play. From all I know about this game it will attract people that never thought about even playing a PC game to PC gaming. People will go out and buy PC's just to play this game. It will engage a huge amount of people into playing it nonstop or just casually. The level of depth and detail in the game is far beyond what anyone is doing right now or has tried doing in the past. You are playing God, down to the last detail and WELL beyond what was achieved in the Sims games. You can't tell me people aren't going to jump all over the chance to play God, in a totally user created universe. I dunno but I see this game having a huge impact, not only on the PC but possibly into other fields. Talk about a create case study for anthropologists. That's my 2 cents anyway.
As for the rest, right on. I cannot wait for HL2 Episode 2, Episode 1 was GREAT and I really like the episodic style they got going on. Plus if they keep the commentary in the game, like they did in EP1, I will surely play it through many times just to listen to it. If anyone has EP1 and hasn't played through with the commentary on, you must! It is like watching a movie with the directors and actors voice overs on, but you are playing the game, it really makes a great experience.
Finally, STALKER. I've been waiting for YEARS for this, and I'm just excited it is finally (fingers crossed) coming out.
Sorry for the rant, boy I had more to say than I thought
