I am working in tiny team (3 persons, 2 coders and 1 artist) and we decided to not bother with version control. We just post on trelo what part of project is modified by who. Then I migrate that improved part to master project and update it in dropbox (yes its like doing version control manually), but for just 3 people setting it is not worth the hassle, esp when your artist may be not quite happy with yet another weird app on his computer. Also manual merging forces me to check and test changed blueprints.
