The Rise of Casual and Mobile Gaming
Hopefully the return of simpler games will cause companies to think about making simpler ones for consoles and home computers - perhaps at a budget price to reflect the fraction of the production costs involved. I'd like to see the return of scrolling beatemups, and shootemups - both genres that have been virtually dead for some years now (even counting the limited japanese arcade releases).
There's a growing number of people including myself who now collect arcade machines and the game boards, simply because the games are more fun. Come home from a long day at the office to play some relaxing starcraft or sprawling RPG? No thanks, I'd rather just shoot a bunch of aliens in a fast scrolling arcade game and not have to think.
