Hey, I just noticed that two Sega Vintage Collections are available on XBL, The Monster World collection; which includes Wonder Boy in Monster Land, Monster World, and Monster World IV. It does not include Dragon's Trap though, which is a downer.
The other one includes Alex Kidd in Miracle World, Super Hang On and Revenge of Shinobi. The only nifty things I noticed about them is that you can play different versions, like US, EU, JPN etc. But I didn't really see anything new.
The sale for this week includes Beyond Good & Evil and Outland each for 400pts, and Might and Magic for 600pts.
Man, I was going to get the Monster World collection but the lack of Dragons Trap put me off. Eh...I own them all anyways
