[quote name='PenguinMaster']I've tried the trials of every single XBLA game and I haven't found a single one worth the asking price. I have two 1600 point cards that I got for $20 total a while back but I can't find anything good to spend them on.[/QUOTE]
I think this might be a generation-gap thing. I grew up with arcades and even though I have MAME and all the classics collections, the XBLA ports of old games are very well done and they're cheap as coffee. If you can't find something you like among the 100 titles on offer, you're either not looking very hard, or you're under 25 and just don't "get" the appeal of arcade-style games.
XBLA is one of the main reasons I bought a 360, and I spend a lot more time and money on the quick-n-simple independent games than the fancy disc-based releases. I was heavily into PC games in the 486/early Pentium days, when PC Gamer magazine would have 12+ demos a month, and many of them resemble the stuff we can get on XBLA for a bag-o-quarters. Nowadays PC gaming is all about army simulations and Warcraft, no diversity at all.
For me, these would be system-sellers if I hadn't already bought the machine: Alien Hominid, Pinball FX, Space Giraffe, both Mutant Storm games, Geometry Wars, Marble Blast, Joust, Robotron, Pac-Man Championship Edition, Assault Heroes, Puzzle Fighter II HD, and more.
Wii and PS3 have some good stuff too, but without demos for everything, it's not nearly as well thought out. The Wii's Virtual Console in particular is full of a lot of crap -- or maybe that's because I'm "too old" to think the Turbo-Graphx16 and NeoGeo are worth chasing.
I'll gladly give you $25 for those cards if you seriously aren't going to use them. I know I would use them! I could PayPal you the money and you could PM me the codes, no shipping required.
