More and more games seem to suck on thier own, but can be great with mods. You have entire platforms like roblox where all the games are more or less mods. How long until the platform itself is community created and managed and the viability of games created by companies dissappears?
I’m not exactly sure if this is what you mean, but I have a couple examples of fantastic community powered fan games that arguably eclipse their inspiration.
Pokemon Infinite Fusion: fan powered remake of Pokemon Fire Red that incorporates a fusion mechanic and has something like 600,000 high quality fan created sprites. They’re now working on a version for Pokemon Emerald
Clone Hero: fan made guitar hero/rockband clone with support for tons of peripherals including drums and vocals, with a huge library of fan generated songs.
