well it depends...
if i can fight trough my way with this project in school, i will make my final work for diploma with it. in this case, it should be ready by the end of spring.
but i doubt that my old fag teachers would like to see chompin' and shootin' and stuff at the university's exhibitions ^^ it depends on them.
if not, i will start it at summer, but the interactive structure will be ready with the diploma anyway.
apart from the interactive part, i need to make the animations of atcs, some 3D model of weapons and alien classes, then to make it's textures and line animation again manually form frame-by frame prints (like 15drawings/sec), plus all the drawings of all the scenes, painting backgrounds, co-operate with a translator, finding music and sound FX, adding the video SFX and other stuffs.
if i start at summer, it can be ready till august or smthng like that.
btw i dont really know what does 'cheesy' means in this case, but as i can imagine the hot cheese stretching on a pizza, i would say you're talking about the time of making ^^
