Ya know, I would have to say my best console was the dream cast. Just with the graphics(back then) and the game play. The 4 player support on one console, and even internet play. It truely was an amazing experience for me.
Right now I am liking the 360 alot, but I haven't truely tried the PS3, so I don't want to put an unfair judgement out there. The Wii is very impressive, but is more centered around simple fun instead of hardcore gaming(true gamers know what I mean). All 3 systems seem amazing(only played 360 and Wii though), and I'd like to have them all, if I had 1 k to spend on the consoles and another 1 k to buy games. So really(not a console), I've been into PC gaming lately. There are more games for PC really, even though not all of them are that great. There are still quite a few games I enjoy for PC and a lot of games I play now are free(stupid consoles don't support burnt DVDs so no free games there).
