Started the PS3 today finally but only played 2 games atm. Of the machine itself imho the XBox360 is a better machine in almost every way. The dashboard I feel is better (the PS3's is messy imo filled with too many options with too little of a description to explain most of them). The 360 was also far easier to setup. The 360 itself also just feels like a more solid product. Also there's the issue with the PS3 outputting to 720p for some reason causing issues with my screen (using my brothers now). On the plus side inbuilt wireless is absolutely godlike.
For games here's my thoughts.
God of War 3 is more of the same but upgraded, which is of course good.
Combat is great as usual and at least the intro was pretty epic in scale, I especially like how they've expanded the wall climbing combat mechanics. Unfortunately animation lock still happens prominently which is just as frustrating as ever. Story wise I already knew bits and pieces of it and so far it's as lame as I feared. Basically I hate how the Titans betray you calling you a 'pawn' as that clearly wasn't the case in GoW2 and there's also Athena being all weird and out of character.With Resistance I gotta be honest, i'm surprised that they managed to get a series out of that game with what i've played so far. Maybe it was because the PS3 had nothing better at the time. *shrugs* It just screams that it was made by a developer who not only had never made a shooter before but one full of people who didn't even play shooters anyway and tried to copy the formulas of very old shooters while designing Resistance.
Except for the noticeable input lag the game has a 'good' kind of clunky feeling to it that helps define the game and the pace of combat. Kinda wish there was some aim assist though, aiming with controller is so hard. >_<
Not as great as I was hoping it would be. 
But still greatly entertaining and over the top.
