While I enjoyed playing the Halo games, they don't hold the high place for me that they do for so many others. That said, I like online shooters and sometimes you have to go where the people are to get a good game. And the people will most definitely be playing Halo 3. Including my young cousins who will no doubt be bugging me until I go buy it.
Think I'll make'em wait another week or so.
edit: Oh, plus these games that no one will buy came out today(I think) too...

The European PS Blog is a lot better in breaking out which stuff is for both PS3 & PSP than it's American cousin. All the minis/PS1 games are for both, only one reminds me of this. Europe also seems to be catching up at all times.
