Some gutsy decisions, new sims are like buses, you don't see any for years, then 3 come at once.... it's funny how success might hinge on getting something out there, unfinished, so that all your work isn't overshadowed by the plethora of new sims. An early-release version needs to grab people and hold onto them, Aerofly FS2 did this well, a low-key release which you'd miss if you blinked, and let the community spread the word. DTG probably don't think that they have the luxury of a slow start, which may work against them. I have my fingers crossed!
The aircraft look very nice, certainly not another 'flight school', but the world looks underwhelming. Maybe they are holding back the best for the actual release, but I did say that I'd need to be grabbed by the lighting/atmosphere, the video leaves me ungrabbed.
EDIT: That final artwork they use in the video, and on their new site, reminded me of something, couldn't think what it was, until a lightbulb went on

Maybe it's a DX13 preview!???:)
