The question comes:
How much money have you spent on WoW throughout your play-life?
I'll go first! (though this is an estimate):
I've recently bought collector's editions, and because I didn't get them in the past I had to pay a bit more, so I could get the pet. (I'm a collector of both mounts and pets)
Starcraft 2: Wings of Liberty CE: $251.99
Starcraft 2: Heart of the Swarm CE: $63.00
Diablo 3 CE: $173.98
Diablo 3: Reaper of Souls CE: $59.99
World of Warcraft: $49.99
The Burning Crusade: $39.99
The Burning Crusade CE: $185.00
The Wrath of the Lich King: $39.99
The Wrath of the Lich King CE: $198.00
Cataclysm: $39.99
Cataclysm CE: $ 64.99
Mists of Pandaria CE: $59.99
Warlords of Draenor CE: $ 69.99
Total: $1,236.90
I've been subbed for over 9 years now, minus about 7 months where I let my main account expire (then minus 8 months from RaF rewards):
Gametime: 14.99 x (9 x 12) - (14.99 x 15) = $1,394.07
I've had 8 recruit-a-freind accounts I bought, mostly for pet/mounts (got mostly durring deals)
Starter edition upgrades: 4.99 x 8 = $39.92
1-month per account: 14.99 x 9 = $119.92
Total: $159.84
I've gotten myself some Blizzcon loot (again I was too late to see I actually really wanted them, so a couple I paid more):
2007 Murloc Costume: $200.00
2010 Deathy: $80.00
2013 Murkalot: $40.00
Total: $320.00
I've bought all the mounts and pets from the shop.. collector
Blizz-store Mounts: $25 x 7 + $30 = $205
Blizz-store Pets: $10 x 9 = $90
Total: $295
I bought the two Blizzard stuff animals:
Wind Rider Cub: $24.99
Gryphon Hatchling: $24.99
Total: $49.98
And I have spent some money on TCG loot cards, though later I bought other mounts and pets through gold:
Pets, Tabards & things: ~$120
And miscellaneous things including but not limited to: Character Transfers, Name changes, Race changes, Scroll of Resurrection, other promotions from real life, etc.
Misc.: ~$500
I feel like there more somewhere i've spent, I just can't think of it now.
