New Temptations

Downloaded the demos for Lucidity and Shadow Complex, two recently released games for XBLA. I got to play them for all of 5 min before I had to go to work. Oh and also a tower defense game called Defense Grid which I played for about an hour. I've been feeling a new XBLA purchase coming on. The barriers to acquiring downloadable games is frighteningly thin. I can, on my couch, simply keep pressing the A button and I will receive games. I don't have to move my right thumb more than a fraction of an inch, let alone get up and find my credit card. Scary. It's really surprising that I haven't given M$ more money than I have. I like to think it's a testament to my iron will and thrifty nature but that thought seems pretty suspicious. I don't know what else could it be?
