If you have a 360, the best deal for these games is easily for that platform. Paying 800 MSP ($10) gets you all three games, including the Genesis version of Wonder Boy in Monster World. It's better than $5 for each of the three games separately on PSN, or $8-9 each on the Virtual Console.
True, but it didn't seem that bad to me from what I played of the demo. I went ahead and bought it, though I may wait until I get something like those Street Fighter IV control pads which have better d-pads on them. The 6 face button layout of them should also work well with the Genesis games here
