Retro's were always meant to recreate Habbo and definitely not having every hotel running Phoenix, with the same catalogue and same website etc. There are not 1 but many factors that would maintain an economy. And one of these is originality. If I were to join a hotel which I knew has a pretty stable economy using my example from my last posts but you only start with 100 credits instead of 100k you might not go there. But! When the 100 credits offer you a complete new scala on features or differences which any hotel wouldn't be able to compare to the choice might be a bit harder!
Well, that's what I'm trying to recreate with my hotel. I will try to recreate the oldschool experience and people may not like it, but there's this Habbo userbase that does LOVE oldschool and that's the group I'm trying to target. And I'm SURE they rather join a stable economy with a 100 credit startup instead of just another Phoenix hotel.
