When I first played it I didn’t get very far into it. But I came back to it a few years later and finished it. The Multiplayer was also suprisingly fun on LAN-parties.
Giants: Citizen Kabuto
It was a kinda janky 3D Action Adventure from around 2000. Back then it had really beautiful and colorful graphics. I remember playing it on my first “real” PC and being amazed by how it looked.
It also stands out to me for being actually funny and comitting to being a comedy game.
Good luck. Let us know if it still holds up today.
