The Collection only includes a scant four games, all of which are either currently available on Xbox Live Arcade or will be soon. Sonic Adventure and Crazy Taxi are both up for 800 MSP ($10), while Sega Bass Fishing and Space Channel 5: Part 2 are both on the way. PC users might be pleased to find these games available with enhanced graphics, while 360 players could grab the whole set or download only the pieces they want.
Sega didn't disclose a price in the press release, but all four downloadable XBLA versions will probably come to a grand total of $40. We'd guess the retail collection will be set similarly at $39.99 for the sake of parity.
I was a fool to get my hopes up.
