You'd think we'd have better tools for this these days wouldn't you?! Global
renaming and context aware renaming etc. What are you using?

pretty torn about this.

I suppose the Quake s/w renderer is kind of nostalgic because it was the
first game to have such advanced 3d features. But, you're right, even the
most basic 3d cards these days ($40!) can render Q2 no problem, so I'd have
to say cut it. I'm quite happy to leave the call entirely up to you though.
I'm not a PC assembler guru so I couldn't add features or maintain it. If we
went with the GL one (which lets face it GL is the new gfx baseline) we
could add new features. I know isnt a goal of this project, but it would be
nice to have the option.

of stock assets are still in PCX form).

Eventually, perhaps we could supply a whole new pack file with different
assets to avoid licensing problems. We could ask some artists to get
involved?

physics fs which has been fixed.

Great. I'll try and build that sometime soon.
