I have had my 720 for about 5 months time and I must say I have seen the lack of good game software first hand. There is always light at the end of the tunnel though... Mostly in the form of emulators.
I went ahead and registered my copy of pocketdos - and have been using it to play a ton of old dos games like ultima and battletech.
There is also a very good nes/gameboy emulator, YameCE(0.38g) - (at techmage's forgotten files) that I use all the time, old final fantasy games - zelda - smb - etc. You can also get a c64 emulator and a msx emulator that both work pretty well.
Just dont let that 206mhz go to your head, you're not gonna be able to run a SNES emu or quake1 very well
