Though meant for another matter, as the name implies, Tuyware's "My Game Collection" (link) was pretty good for anything tracking from what I used of it some years ago. From my experience, it was good for its tagging system, the accompanying filters system, and the ability to add custom "platforms". Do mind, however, that some useful functions are paywalled, and they don't offer a single payment version, only a MTX-based payment to unlock those functions.
