I would hope that Single Player doesn't go away. The single player in a game is usually my most favorite part. The multiplayer is just an added bonus to me.
The single player situation had been running in my head for the last 2 years,me trying to find good games that are single player and thought that almost all games might be heading in the MMO's direction well i am pleased to say in my opinion the studios have worked out their sums and found that its a huge market in the single player department, so now i can and will breath easy.
