SEGA fans will be in nostalgic heaven with the latest humble bundle, which includes the Dreamcast Collection, NiGHTS Into Dreams and Sonic & All Stars Racing Transformed for as little as £0.64!
As a fan of the Dreamcast myself (which probably would have been the best console of all time if it wasn't so far before its time!), I'd suggest buying in at the lowest tier for maximum value. Especially since Sonic & All-Stars Racing Transformed makes this a bargain all by itself. However, you can beat the average to also unlock Empire: Total War (not one of the best) and one faction in Company Of Heroes 2: The Western Front Armies -- to be honest it might be worth holding off until they reveal the bonus games. I'd probably predict Jet Set Radio at the very least, but we'll see.
