Sega Smash Pack is just a really bad collection though the only good game is Golden Axe on the collection.
Golden Axe looks well on the GBA and the sounds are good if you have played the Mega Drive version you may notice little difference.
Ecco the Dolphin is featured in this to but this game sucks i never found it fun and to me it is not a Sega classic.
Sonic Spinball one of the worst Sonic games i have played Sonic in a pinball game this was bad back on the Mega Drive and still is just a terrible game.
If you were to buy this i would only get this for Golden Axe because it is a top quality game.
