Amazonís deal of the week for downloadable games is really focused on gamers like me that grew up gaming on the Sega platforms. The standout deal, to me at least, is 80% off SEGA 48-Game Mega Arcade Pack.
I'm not going to list all the games in the pack but some of the highlights (that I remember playing as a kid) include:
All that for $7.49 (instead of almost $70).
The other download deals include Sonic Generations, Renegade Ops, and the 4-Game Dreamcast Collection (which includes Crazy Taxi, Sonic Adventure DX, Space Channel 5 Part 2, and SEGA Bass Fishing) for $7.49 each. Plus Sonic the Hedgehog 4 Episode 1 for $4.99.
If you're not into downloadable games then you might want to know that the GOTY edition of Red Dead Redemption for PS3 and 360 is $30 this week.
