I'd be keen on this too.. bought 10 copies of the games for my friends and i and all the dlcs. Ended up dropping about $100 on it because i love this type of game and saw myself playing it a lot.
well players will have accounts in Among Us 2- but accounts don't currently, and might not be ....able to be implemented into among us (1), as the game was never designed for that(which is the entire purpose of among us 2, to be built to last and expand upon), though i suppoossseee, you could submit a receipt from steam or whatnot to innersloth......those would just suck to go through, so you likely will not be able to transfer stuff, but i don't code, im just thinking logically
