It's either extras-devel, or extras-testing. Since the data files for this game are loaded by the user in either your home directory (internal mass memory) or the memory card, the optimized status doesn't really affect the space used. The actual binary and config files for Quake 3 that would reside in /usr/bin or /opt/bin are REALLY tiny.

When I was trying to make space on my /root partition for the last OTA update I uninstalled Quake3 and it didn't make any noticeable difference in the root space consumption.
