This is interesting and has come at the right time, a conclusions I have come to developing apps is that the best business strategy over the sheer lottery and randomness that is mobile development is developing 'long-term' I.P. My large projects can require long development cycles, if a unique and compelling I.P is created, one can create subsidiary quick turnover projects.
Iv'e been working on a mobile 2d shoot em up set in the same game world as one of long term projects, this NEW 3d shoot em up engine, looks like a nice step up from that project below for the future.
Iv'e got a few ideas about using models with baked in textures, matched with the skybox so I can get the same thing that is in my 3d program into this 3d game engine, net result if done right is a game with beautiful visuals, regardless of the engines capabilities.
I think what will make or break this program is functionality, total level size capability, enemies or game content size in level or on screen, if it has any flaws, like extreme file size for relatively small amounts of content, or if you can only have one level per game, or requiring super high computer specs to play for what might perhaps be a low spec game etc.
possible features?
altering camera position, example, go from isometric view to behind view with a smooth track between, also a random movement change, so if we have a side dolly shot, the camera can move slightly (think handheld cam moving slightly, giving a hand held camera feel, as if its not fixed in a tripod) same goes for the dolly track, capability for random angle, this tells the player, yea this is 3d, not sprites viewed only from 'one set' position. It helps sell the 3D perspective more.
'circular' game play, 'central' gun 'surrounded' by incoming waves, beach head game style.
Lots of potential for sure. I think the market is open to this, if it is brought correctly together, potentially its something that could generate a lot of interest.
If any user creates a showcase project in this, it will give it the gravitas to push media interest. It will be interesting seeing what users can come up with.
