I like the roller derby/rollerblade mario kart wth sexy 80's chicks in leggings idea from a few threads ago and think it would be great with the gatcha formula. Would need great character designers and 3D modellers though.
Do you think aggies could collab on a gatcha? Are there enough talented character artists here? Revenue split would be based on how many characters designs you make (must be voted in unanimously by the other devs to ensure quality), with bonus shares for designs that get more fan art made of them.
Maybe there's light melee combat and each skater has a unique melee weapon like how the girls in Blue Archive have guns, so you have another distinctive thing to add to the character design.
Characters would have:
>unique personality
>club affiliation (gear heads, atheletes, crafters, artists, nerd gamers, laboratory scientists, etc.)
>unique style (goth, prep, punk, loli, hag, genki, tsundere, etc.)
>unique melee weapon or grenade/flash/smoke bomb, etc.
Would be a lot of work writing up and polishing and making key art for the VN dating sim parts for each girl.
likely wont go anywhere but this would print money if done well
