Prototype was pretty much garbage, though, and the fun wore thin really quick. The buzz reflected that and the game sold or didn't sell on it's own merits.
There's plenty of room for 3 high profile games in a month, but ~10 is starting to stretch it, especially when two of them are best selling franchises that people still actively play online.
Red Faction had it's share of problems and was far from perfect, but it made up for it by being really fun. If it had been crap, the sales would have been considerably lower. My point was that there was time for the buzz to build up for Red Faction, because the next awesome thing was pretty far away. It had the chance to stand out, show off what it can do and rank up sales, without some huge franchise like Halo breathing down it's neck.
