even if you don't "learn" anything, you'll know if something is missing from your game (especially from BERT as they shoved all their money in graphics and music, leaving zero for UI, writing, and gameplay elements)
also if you don't have a shitload of money you'll have to either do a bunch of graphics/art direction or sound/music... because without those things the game is utter shit, yet those things eat up budget
