Basically I have three things that I play games on;
A PC, a Gameboy, and a PSX.
I did have a PS2, but I threw it away. Why? because i've always hated it. To be honest, I don't really like any game console except the PSX. The PSX is the only game console that has made me happy.
And most of the time when you play online like Xbox Live etc. Most of the people who play on there are probably 11 or 12 year old imature kids who think they that they are all hard and think it's funny to constantly insult you or annoy you.
If you go for the PC online. The people I talk to online are mostly mature, friendly, and always play fairly. But you can get the odd one or two idiots on PC as well. =S
