I'm in the process of planning (for next year) an RPG with stories and themes in the vein of the Earthbound/Mother Series RPGS. For those of you not in the know, Earthbound was the second in a quirky trilogy of games for the NES, SNES and GBA where the setting was relatively modern, baseball bats and psychic powers replaced swords and spells, and the plots usually had to deal with kids discovering and thwarting machinations of evil aliens. All the while, it presented itself in a goofy "Americana" vein of visuals but the games mostly played like Old Final Fantasy or Dragon Warrior games before frills were attached. Still alot of fun and memorable.
The problem is I'm looking for a system to run it with, preferably something simplistic and fun to adapt, but lack any such system.
I *DO NOT* want to use 3.5/4e/PF/d20 Modern nor do I want to use MnM variants (the former are fun games but not stylistically what I had in mind, the latter nearly frustrated me to tears in just trying to get the math right when buying super powers,) and currently, I'm reaching out trying to find any opinions or directions to take my research/planning in.
Anybody know of a system or system that may work for this? I've been pointed to FATE and Risus so far, the latter of which is looking fun, but I want to explore more options, if anyone can direct me.
