more to the point i think that i lack now the patience to get into a game of old, mostly due to the fact the tastes on gameplay, interfaces and interaction are more refined than when i was a kid; but also because the games available through emulation are so many that when you don't get instantly into one you pass to the next, a fact that could not happen years ago when you actually had to save money for each one of them.
the only game i found and loved through amiga emu, so far, in 10 years of me using winuae, is Pang, that i can think of. who knows?
