Could be legit for all I know but an ICO before you have so much as a screenshot or a tiny clip of the game to show... Reeks of ulterior motives, sadly.
OK, lets say just for the sake of argument that we don't have any game done yet - absolute 0. Why would that reek of ulterior motives?
We have a plan, we have all the tools, we have a team of coders and a team of designers ... why wouldn't that be a viable plan?
So ... in this case we need the money to pay for the work that will be done, and to buy more and better equipment.
If this ICO is successful at least +20 people would get a job on a permanent basis, a team of designers would get hired, some other people that can help with different skills would get work, ...
Why does it reek of ulterior motives?
There will be a trailer finished in UE 4.5 until the end of the week
