Sega America hosted an iPhone gaming event earlier this week, and the lineup of titles they've got coming to the App Store this fall is a gamer's dream: Chu Chu Rocket (my favorite Dreamcast game!) is coming to iOS, along with classic side scrollers Gunstar Heroes and Altered Beast, Sonic the Hedgehog Episode 1 (the brand new 2D version of Sonic), and a free-to-play strategy/RPG MMO called Kingdom Conquest. TouchArcade was there at the event, and they say that Chu Chu Rocket is all you hope it will be, the new Sonic looks excellent, and Kingdom Conquest sounds like an intriguing mix of genres. Card battling, empire building, and RPG questing all built into one Sega-published free-to-play title? Chu Chu and Sonic already have their pedigrees, but it doesn't sound like you can go wrong with that last one.
What a lineup from Sega for this year -- I'm actually more excited about their iPhone releases than I am about anything they're bringing out on consoles or any other platform. Unfortunately, there's no mention of Game Center in any of these previews, but all of the games seem to have multiplayer of some sort, from 1-4 players over both Bluetooth and wifi. So it's probably a pretty good presumption that they'll be Game Center-enabled in some way.
So lots to look forward to in the next few months. Should be fun.
