[Sugar-devel] SugarGames, GTK3 and fonts ?

[Daniel Narvaez]

Personally I wouldn't use gtk to write a game. As far as I know, a 2d
drawing API (cairo) is pretty much all you are going to get from it.

I would either keep using pygame, which doesn't integrate very well with
gtk (and hence sugar), but it works in the end.

Or even better I would use sugar-web. A wrapper should be possible even for
very old version of sugar, in theory.
