Okay okay... I found this via googling and such... Also, please bare with me as it is past 3AM right now... (This is driving me slightly insane XD)... Anyways. There was an old game (assuming late-ish 1990s) that I played on the PC, I believe. It was a 3D game as well! It was some sort of racing or car-arena game... I just remembered playing the crap out of it and here are the lists of things I remember from it:
Castle-theme (The maps I played one were all castle-like arenas type of thing). Stone-like, castle flags, etc. All that such.
Many different modes (Including Racing, Deathmatch, CTF, Team stuff, etc).
Option to set how many AIs. (I remember driving about the map finding no targets due to setting only 1 enemy AI).
Power Ups. Including a Wrench for healing/repairs, shields, nitro (I think), weapon power ups (NOT weapons in general), etc.
Did NOT use realistic vehicles (Used its unique vehicles). Also, I do not remember any story mode nor any characters. It was more of a straight forward into game type of fun. That or I did not bother said stuff.
Green animated arrows on specific spots on the ground which boosts speed when hits. (Useless most of the time. Useful in races).
And so on... Anybody knows what I'm talking about? I've been looking for it and really wanna get it again! Tis was a fun game.
