Come to think of it I think I've only killed the Succubus too. I always did the same grinding the hell out of Alis early in the game because she'd get the crap beat out of her being alone and usually parties up against her getting multiple hits to her 1 which bugged the hell out of me. I'd make sure I could with some kind of ease make the run for a partner to have someone to run with to help kind of even the odds.
I know I will never own a SMS again, it's just not worth it and I can't commit the time, plus the games of which maybe a 1/3 I really love came from the UK and I'd rather not pay that again through ebay now they all use that crap global plan which makes for like $20+ shipping on an item. The sonics, streets of rage 1+2, the castlevania clone, golden axe warrior, and a few others I loved right up there along with the US gems like the Wonderboy titles, PStar 1, and various others, a good bit happily on this Sega Master/GG handheld I own (thankfully.)
I'll play PS1 again, when I decide it's time, I'll get that emulated Collection cart for the GBA, but when I do I'll make sure to get the manual and the fold out map/item+gear guide so I'm not just straight up screwed.
