Unvanquished VS Cube 2 (Sauerbraten)

I would recommend Unvanquished instead. It's basically the same game but FOSS, much more polished, and there's a small but active community. Servers are often empty, but people will eventually come if you join one and you can play against bots in the meantime. Source: about 1 year ago

I enjoyed Tremulous as well. There's currently a sort of revamp (ignoring GPP/Trem 1.2), called Unvanquished. https://unvanquished.net/. Source: over 2 years ago

Unvanquished the fork of Tremulous (who's not developed anymore) could fit. Source: almost 3 years ago

You're probably thinking of Tremulous, which is also forked as Unvanquished. Started life as a Quake 3 mod if I remember correctly. Source: about 3 years ago

This makes me want to make a Lego Sauerbraten map. Source: 5 months ago

Out of curiosity I landed at http://sauerbraten.org and was not disappointed by the video. - Source: Hacker News / 5 months ago

The editors are basically immediately off limits for anyone who wants to mod the base game rapidly for their own enjoyment. A concept like http://sauerbraten.org/ is interesting, but seems to not have taken off for various reasons. Lesson learned I guess is that being able to customize is not everything. - Source: Hacker News / 8 months ago

N-Space 2 will let you build on multiple levels of detail. Instead of a single size of cube, there is an adjustable "grid" which scales from 1/16 of a block to 2 blocks. This massively expands the possibilities for modelling. I was inspired by the Cube 2 engine, which has a similar approach to building on different levels of detail. Source: about 1 year ago

This might help, sounds like an unreal or quake game. Maybe Cube 2 Sauerbraten as well. Source: over 1 year ago
