kids in school do you want to play with antimatter bombs?

here your stuff:

https://www.unrealengine.com
https://3dwarehouse.sketchup.com

(just a personal thought. this shouldnt be a command to someone to do this.)
i know tons of models there are horrible and cant be used. just pick the good ones out, and maybe ask for permission. but in overall, if you are in school nothing would happen at your age and position if you do use there 3d content for your realtime adventures. if you are smart, write down the owner of model and put them into the credits.

have fun with this antimatter bomb!

and i trust that gamers will do one day the smoothest games.

so good luck on your way and do some kickass stuff. oh, dont be frustrated if something dont work like it should. some things will need its time.

so then, i wish a happy kickass time. :-)
