I like short games, there's room only for a few time sinks in my backlog.
I agree that Sega isn't quite what they used to be in their first party days, but the game industry is in a terrible shape right now. At least Sega still has stuff like Valkyria Chronicles and quirky quality releases like Rhythm Thief, and they're actually putting some effort in re-releasing some of their old classics. Compare that to a publisher like Konami, who have fallen so far from their previous standing that it's just sad.
There could actually be hope that Sega would release those lesser-played games like Shining Force CD and the full SF3 on digital platforms, but it sure would have helped their chances if Nintendo had announced a Wii U Virtual Console service with support for Sega CD and/or Saturn. But instead it seems that Nintendo is keeping any possible Wii U VC service under wraps for now, so there's no telling even if they will extend the available platforms from those currently available on the original Wii service. Sure, there's Steam and everything, but those just don't have a similar scope for retro games.
