awesome :) i have coppercube studio too i think or the not most expensive extension but the secon one :D
However i really like that you'Re using the modified blender engine UPBGE i also have it, but due to my lack of experience with blender i didnt really tried it yet. You are aware of the second Blender engine that is around ? its called Armory i think and you can download it here on itch as well for free :) Further i really like you are using FPS creator and ggm i made 3 game using gameguru classic one with gameguru max yet, thou i have plant more :D AND im trying this modified FPS creator engine Black Ice Mod Engine, it freatures more stuff then the original fps creator and the developer is constantly working on it, it costs only 12 euro ....
AND i have a recommendation for you, if you like the approach of fps creator, there is another engien, you might enjoy, its free and called Easy-FPS-Creator CE Easy FPS Editor CE v1.10.5 by CG8516 (Clark) I certainly really liked it and still do and after my gameguru games its was something new, and funnily (?) extactly these free games ive created were my most succesfull till today, counting views, and downloads, not actual money sadly lol :)
best regards, love and peace <3
id apprecitate and be really happpy if you'D consider giving my lates Easy-fps-editor game a try: Behemoth by -X-ScornGames
or if you'd like to check my gg games i would suggest: Grave Digger by -X-ScornGames but its actually rather short, and its ALL ABOUT THE ENDING :D
