Radon Labs has ca. 100 employees and enough space for another 50. Their bread and butter is low budget contract work (aka horse games for little girls). They always have a couple of these in the works. The positive effects are stable technology on multiple platforms, no licensing costs for it because they own it, and a very efficient production pipeline. I got a tour through their studio near Alexanderplatz in Berlin earlier this month. Three things they do differently than most Euro studios seems to be a very short pre-production phase, internal testing from day 1 and extreme pragmatism.
Drakensang is certainly in the green with 450k and counting, at a rather low budget (ca. 2.5M EUR I think).
