Sorry for stepping in so late.Since I've played both a few time I believe I can reply the OP question, in my opinion CO2 is in fact lighter than Vinhos.
Although I prefer heavier games that doesn't necessarily means that CO2 isn't a lovely experience, it is! In fact I think that it will appeal to a much broader audience (well not for those hate raters) than Vinhos, and would probably will have a larger print run.
If you finish it very fast and like meatier games ... well play 2 CO2 in a row :D
Good luck with the release in Essen Vital!
