I'm just going to go ahead and apologize now for the ridiculous amount of achievements and I have come up with.
Seriously like, be prepared. It's gonna get crazy.
The celebration is getting crazy on the party thread from Elwood. Quite a number of big names like Saggitarius, Pete, Rumi, and even Calvin Blackmoon have popped up! Keep an eye out on the forums throughout today to see who else shows up. ;)
We had some battle achievements planned but weren't able to do them at the time, but they (along with a lot of other new achievements) will come soon. <3 Ariel and I have a spreadsheet and document full of ideas for future achievements (beanbags, clothing, games, etc) that we are going to push out over time so it isn't all INYOFACE.
Again -- thank you guys for the feedback though on the anniversary. :) and I will look over this board together and figure out things to do in the future based off it and what not.
