Only read a few certain ideas but I gotta go to sleep... 3 Ideas that really stood out from the ones I read.

1. Triple Triad card games with booster packs!!!! OMG reminds me of MTG back when I was a kid. A real good innovated card game with booster packs could drive players to spending some gil and also making some gil by selling/trading cards.

2. Anima potions are a great fucking idea. I like Anima, no need to remove it. Use it sparingly or just use it at will and spend all your gil.

3. Vanity/Cosmetics Costume items that go over your real gear but doesnt affect stats. Make everyone look different so its not the same red haubergeon army everyone you go... face paint / funky mounts / hair dyes / a huge baseball bat instead of the same old tired Ifrit axe...Maple Story uses this but with real cash. I disagree with a cash shop, instead use gil. 100k and you weild a baseball bat instead of Ifrit's axe for 14 days. Hell you can even use packages, look like Cloud Strife for 14 days for let's say 500k? I mean we look at these tired character models for hours/days/weeks/months at a time. I am sure people can see the value in a little variety. If you like this idea about a vanity/cosmetics shop LIKE this post. Just trying to see how people feel about it.
