Now there's a line I never thought I'd read.
But in all seriousness, I'm in the same boat (not the making Dacid look loaded). While I have the consoles, I lack the games and a means to play them properly. In the case of AH3, I don't have a PS3 stick (still need to dual mod my 360 TE) and I haven't bought it off the PSN. GG and Melty, I lack the games and the proper equipment to actually play them properly. Seriously, I'm not going to try to play GG, Melty, 3S, ANY 2D fighter that isn't on an HD system on my HDTV. I don't have a CRT to play them on, so I can't really play them properly. Hell, the one long session of Guilty Gear I had during Fanime was the last time I even touched GG regardless of interest.
If I had the actual means to practice and put in the effort, I'd gladly enter the other tournaments and play seriously. But until that day, my entries in Arcana and Melty will pretty much remain Pot Donations. And in the end, I don't really mind that.
