a minecraft like engine was my first idea
but i could not find a engine that delivered an easy way to put my data into it
so i switched to
blender the game engine that is included there has a bunch of online tutorials about FirstPersons-Type games, mulitplayer, + the engine itself has many options to make stuff look nicer but i did not got into that
i just put a big floor and some base blocks that have a color and emit some light (avoids putting lamps into ufos)
the next step is a small python script that reads the config/terrain/map files and copy/position/stretch the base blocks (the small ufo has 13000 cubes, after optimization its only 150 cuboids)
there are surly better ways to do this but its as i said this is a prove of concept in this stage
if someone is interested i can upload the original blender file
multiplayer shootout should be possible according to the tutorials i saw
new textures hm if there is a trick to determine what the backside of a sprite looks like and there is a new drawingtechnique (full MCD-entries as 3d polygon instead of cuboids) one could do that
lightning no idea how to do it differently/better i think one could attach a (flash-)light to the player
as you can see now i installed blender like 3 days ago and am a bit unsure what and how it can do stuff
