Hey BigStans, no i haven't enjoyed Leisure Suit Larry Reloaded, but i never enjoyed the original first game either, if they manage to kickstart another of larry's games I might consider helping them for the third and fifth games which i did enjoy. On the other hand, i think the remake is quite well done.
I know Visionaire and Unity are two different engines, though Unity has put a lot of effort into making the engine friendlier and better, it also supports pluggins made by users that expand its features and help by making certain things with ease, like the adventure creator kit mentioned before which makes the engine work quite close to how visionaire works, and you can export to a wide range of devices which is a huge plus.
I remember Ogre being a render engine not a game engine and UDK would require a hefty license fee for commercial work and needs far more coding to be done and i would think it's intended for big studios, though i don't know if it's suitable for adventure games created by really small teams.
It's unfortunate that Visionaire is kind of a hobby engine, i love it so much but the updates and features are years apart, and it's kind of sad to read from one of the developers saying the games made with it have a small market and that is a reason why development is kind of a hobby.
I'm not so sure about small market these days? Adventure/puzzle games seem to be, becoming increasingly popular, all the time & with the help of kickstarter giving some of the old pioneers of adventure games a chance to make more p+c games, which tell tale & daedalic have already been doing a grand job of making them quite popular to a much less nostalgic, younger crowd (nostalgic, being us old farts), which in turn has led to some of the old classic games of the 90's being played again or revitalized on platforms such as nintendo ds; for example
Also I think the (re-)introduction of complex & flexible narrative choices (as seen in: walking dead, for example), which allow the player to change & adapt the world & storyline through actions & dialog choices is a huge step forward for adventure games. Having said that, I realize that we used to have games like that back in the 80's, albeit, they were text only based games
Most adventure games up until recently have mostly been very linear, with wacky puzzles, deep pockets & crazy story lines.
it would be nice if VS had a few more developers, to speed up the time between updates & a bit of a marketing brainstorm session on how to make some paper to pay said additional developers; either that or find some more developers who are willing to work pro-bono.
udk is free for non-commercial (freeware) games, then it ranges from $99 upwards. I think $99 & 25% of game/project sales or something?
