I am #{italic}##ANTIQUE_WHITE#DarkGod#LAST##{normal}#, the creator of the game and before you go on your merry way I wish to take a few seconds of your time to explain why there are microtransactions in the game.

Before you run off in terror let me put it plainly: I am very #{bold}#firmly #CRIMSON#against#LAST# pay2win#{normal}# things so rest assured I will not add this kind of stuff.

So why put microtransactions? Tales of Maj'Eyal is a cheap/free game and has no subscription required to play. It is my baby and I love it; I plan to work on it for many years to come (as I do since 2009!) but for it to be viable I must ensure a steady stream of income as this is sadly the state of the world we live in.

As for what kind of purchases are/will be available:
- #GOLD#Cosmetics#LAST#: in addition to the existing racial cosmetics & item shimmers available in the game you can get new packs of purely cosmetic items & skins to look even more dapper!
- #GOLD#Pay2DIE#LAST#: Tired of your character? End it with style!
- #GOLD#Vault space#LAST#: For those that donated they can turn all those "useless" donations into even more online vault slots.
- #GOLD#Community events#LAST#: A few online events are automatically and randomly triggered by the server. With those options you can force one of them to trigger; bonus point they trigger for the whole server so everybody online benefits from them each time!

I hope I've convinced you of my non-evil intentions (ironic for a DarkGod I know ;)). I must say feel dirty even doing microtransactions even as benign as those but I want to find all the ways I can to ensure the game's future.
Thanks, and have fun!]], math.min(900, game.w))
