Probably not much in the AA/AAA space, but plenty of indies. The Doom engine (and GZDoom, which is the most common Doom engine derivative) is GPL and there have been multiple commercially successful games released using it. I know at least Hedon[0] and Hands of Necromancy[1] sold enough copies to warrant a sequel.

GPL vs LGPL definitely isn't a blocker for a commercial game, in any case.
