Unreal 4 Engine has taken 9 Years to develop.............. 2 and 3 were just pretty heavy tweaks of the original, 4 is a from the ground up job. Now if we could have that Unreal engine or maybe the latest Cryengine, SDK is free for non commercial use by the way.
From a Radio 5 program in the early hours of the morning, quite a few Independent and small game software houses have given up or in a couple of cases gone bankrupt, income is down for the likes of WOW. The cost of developing a new game came up in the discussion backing of a few million dollars was quoted as about average!
I seriously doubt N3V's shareholders and owners are going to take any risks at present with the current abysmal financial state of the planet.
I also doubt that they make much of a profit by the time they have paid for staff salaries, programmers are not cheap, payment to the likes of Jointed rail, Ocemy SirGibby and the S&C crew, for producing the payware, N3V may not get much if anything from that, may just be a publishing platform, cost of premises, rental for the flakey servers, taxes and overheads like electricity etc.
