friend, it was the fault of FPS's for antiquating platformers to kiddy games.
I do not agree. FPSs have been extremely popular - And mature since DOOM, probably even before. Platformers aimed at kids have almost always been the best selling and most acclaimed of all time, like many of the earlier Mario platformers. Stuff like Call of Duty was more of a PC thing for years and years, while Halo was always most popular in places most people would not even be interested in Sonic games would play, such as large parties for LAN stuff, which also happened to Call of Duty a lot (just on PCs).
Still, my point was not that Sonic games are kiddy now, it is that they are lame. The stories are almost always about giant monsters that overthrow Robotnik now, and while the games never had strong plots, they have only just gotten more confusing and convoluted than ever.
Probably the worst thing is just how much of a stark contrast the gameplay is to the plots now. It is all about memory and precision timing, which the series was never about prior, unless you wanted to unlock extra features or get higher ranks. Oh that, and how Sonic Team is probably the worst 'big' developers out now in the entire world.
Half-Life is better than anything Sonic Team has done since the Mega Drive. There, I said it.
I like Sonic Adventure 1, 2, ChuChu Rocket, NiGHTS 1 and Phantasy Star Online more than Half-Life.
