If I'm being honest the first thing I want in the new generation of gaming consoles is the ability to play with people on other consoles and on PC/Mac. The reason I say this is because I absolutely hate that I have some really great friends with whom I play a lot of online games.
On one hand I play a lot of Killzone 2 online and I made some great buddies on there. Not all of them have an Xbox either through financial reasons or maybe just a preference to PS3, on the other hand I also play a lot of halo 3 as well and I have a stack of people I enjoy playing with there as well. That's all well and good you might say those are both console exclusives and you're not going to get those cross platform but then I also have call of duty on my Xbox. I play that more often than any other game and I find myself thinking about how great it would be that I could take my Killzone buddies and my halo buddies and make them my call of duty buddies.
Imagine in the next gen games, rather than worrying which console had the best online community the only thing you had to worry about was which console version had the most ideal control scheme for that kind of game. For instance I like the Xbox controller for racing and first person shooters but I prefer the PS3 controller for fighting games.
They done cross platform before on the pc and 360.shadow run is one example so let's see more of that next gen and across all the formats
I opened a new topic in system wars so bounce on over there and have your say(link below)
