I recommend buying an Amiga, and getting stuck into a game that'll keep you occupied! I'm currently wading through Dungeon Master on my A500. Then again, I could never use a PC as my Amiga, it's just not the same. You need the feel of the mouse, the clicks and whirrs of the disk drive, and the smoothness of the experience. For me, no emulation comes close.
(Gratuitous plug: In case it's of any use, I have some quite nice A500s in my shop at the moment - let me know if I can help!)
