Free Windows XP 3d Game Reccomendations

Hello! I'm new to the forums, just joined today, but I was curious, do any of y'all know of some free 3d games that'll run on XP? I like first person games in particular, not sure why. The computer i'm running is a 2007 Dell Inspiron 1520 with XP SP3 (technically the custom SP4 update). Thanks in advance!


Also, as a token of gratitude, here's a little car y'all can have!
