Good call on that Sega Saturn Vampire Savior, dude. I have Vampire Hunter on Saturn and Chronicle on Dreamcast and have enjoyed the crap out of them.
Adventure island is one of the best PCE games evar
So far I'd pretty much have to agree with you. (But I really like the pinball games, so it's a touch call...) I like how open world it is despite being a 2D platformer. I haven't played any of the Wonder Boy games besides the first one. (Thank you, other game called Adventure Island.)
Btw, how do I get those "?" Items in the shops? I can't seem to buy them even if I have enough gold.
