As with Wario games, I've only recently got into Kirby games, via emulators. 
Boy was I missing out. 
 
I've gone from the beginning and played both Kirby Dreamlands on the Gameboy as well as the NES Kirby's Adventure, and I'm now on Kirby's Dream Land 3 on the SNES. Even though it came out after Kirby Superstar, since it's the 3rd "Dream Land" game I just went for that one, but I can't wait to play Superstar Saga. Apparently it's one of the best, if not the best, in the series.
