I stand by my description of these as "big" releases, as it's a relative term given the PC landscape is flooded with no-name titles like Princess's Garden, etc. No, it's not huge/groundbreaking ala Half Life 3 or something, but these are 3 highly rated console games that PC only gamers (such as myself) are greatly anticipating. Of course you have people complaining about these games being "ports" when if you plug in a x360 pad the gamer couldn't tell the difference between the original or the pc version. And while the occasional port is lazy (GTA4, which I still managed to play thru without problems) other ports are superior to their console version (Mass Effect, Last Remnant).
If you didn't like even the console version of RE4 you should stop playing games because your soul is dead.
Batman:AA is like Splinter Cell+. PennyArcade wholeheartedly recommended it and I almost never disagree with those guys. It's not based on a movie, and from what I've read it's one of the best brawler/stealth combo games ever.
RF:G just looks like pure fun. Consider this nugget from a blog: "I made over ten attempts to secure two hostages near a wind farm, failing every time, until I was so mad that I just backed an armored truck through the wall of their detention center. As I drove away, there was something compelling about the old woman laying down suppressive fire with the minigun. The old women I'd been sent to rescue had been arrested trying to sabotage a power plant. Because I'd attempted the mission so many times, I know that the people you need to rescue are randomly generated. Even so, I was glad that my successful run - the canonically valid one - had taken place with these two in tow. What's their story, I wonder. What had happened here that two women in their sixties had decided the best course of action was to start blowing shit up?" I approve this message.
Anyway I'm still up in the air, but will definitely at one point or another procure all three, it's just a matter of priorities. RFG is losing ground to BAA at the moment.
