Gamers Xtreme (Glacier928): "Over the course of this console generation’s life-cycle, we’ve seen a ton of downloadable titles hit both the PlayStation Network and Xbox Live Arcade. Currently owning over 140 downloadable games available for both platforms, I’ve decided to sort through my catalog of titles and list which ones are entirely worth the purchase."
Oh how I am bit sad to see that DeathSpank is not there. Although the third game was a ot of the same and not super great, the series is still excellent and the first two were outstanding. Great list though.
Outland is awesome sauce like no other. I love the MetroidVania-style gameplay and the strategy behind it is brilliant. And it was on $10.
Would like to mention if you haven't played Scott Pilgrim vs the World you ought to. It's a huge tribute to cclassic gaming like Mario, Streets of Rage, Zelda, and even it's cheat codes are derived from real games like MK's Blood Cheat and more.
This list was comprised of games that are available for both PSN and XBLA. Shadow Complex is an XBLA exclusive, which is why it's not here.
The Walking Dead I've heard a lot of praise about and just haven't gotten around to it. I'm planning on playing that soon though.
