Greetings from a long-time player. There is another thread that allows players to calculate their "age" based on a number of factors. It's a great idea, but I don't think it goes far enough. So I've come up with a more extensive way to compare yourself with other players in the community. I've tried to create a balanced scoring system that takes into consideration a wide range of factors. You can only count what's on your main character.

Here's how to calculate your score:

1 year of having an account = 5 points (game debuted April, 2010, so max is 8 years)
1 legacy achievement = 1 point (max is 6, as far as I know)
1 level 100 sprite = 2 points
(For gear, event gear and shadow lair gear counts double. Prize box gear and boss gear counts for the regular 1 point.)
1 5* sword = 1 point
1 5* gun = 1 point
1 5* bomb = 1 point
1 5* helmet = 1 point
1 5* armor = 1 point
1 5* shield = 1 point
1 5* trinket = 1 point
1 artifact = 1 point
10,000 prestige points = 1 point
10 days of playing time = 1 point

So, here's my score:

8 years of playing = 40 points
6 legacy achievements = 6 points
3 level 100 sprites = 6 points
5* swords = 21 points
5* gun = 16 points
5* bomb = 10 points
5* helmet = 39 points
5* armor = 39 points
5* shield = 12 points
5* trinket = 9 points
11 artifacts = 11 points
76,360 prestige points = 7 points
277:08:21:53 playing time = 27 points

Total = 243 (I calculated in my head, so I hope I got it right.)
