Since I have been looking forward to Dragon Commander for a while now — finally a truly innovative game — it seemed not a bad place to give them some additional funds. Backed them with 65$ for both games.
Regarding Original Sin, the only thing that seemed a bit too old fashioned for me is the square grid design: with few exceptions, 90° angles are synonymous with boring (city- & building-) architecture for me. That aside, it seems to share quite a lot with the Neverwinter Nights games, which is a big plus in my book. Also, I like the interactivity they implemented for combat, which should keep that aspect engaging longer than in other RPGs. Overall, it does look promising! Not sure when I will have time to actually play those games, though…
