I always check how long a game is before I start and hope it's <20h. Nowadays I wish more JRPGs were short and sweet (Chrono Trigger is the perfect example), then maybe I'd play more of them. The only games in the last 10 years or so that I've invested a lot in are TW3 (~100h), FFXV (~120h), Dark Souls (~70h) and LR (~80h).
