Holy Bacchus, calm down man! Don't go attacking NLT just because it is an RPGM game. It is actually one of the best games on this site. Not to say BaDIk is a bad game, they are just different genres.
It's not that it's a RPGM, it's because it's giving some people a false impression of update speeds. People see the regular updates of ToN and think, "that's how all games should be", but they can't. 90%+ of games are made by solo devs, many of whom are working with hardware that can just barely handle the rendering strain, whereas I'd suspect that NLT is working with a team and high-spec hardware because they've been around for a while producing 3D adult comics and so have likely generated enough income over the years to be able to afford these things.
DPC, on the other hand, is like every other dev in that they work alone on their game but unlike most he has high-spec hardware and so can produce lots of high quality renders and animations, but it still takes time to do so. Their game is also entirely built on renders that they produce, whereas a RPGM game is mostly produced using pre-made or custom made environments at the beginning of the production cycle that are then repititiously used in every update and the actual number of new renders per update is minimal in comparison to a game like BaDIK.
Finally, as
always86 stated, much of the time spent in an update for a game like ToN is running around these pre-built, top-down environments seeking items to unlock a couple of sex scenes and so there isn't as much difference and variety as you get in BaDIK.
I know people like ToN and that's fine, but it's never a fair or even apt statement to say that its regular update cycle is something all other games can do.
