Mission Équitation Online: Mon club sur Internet

Summary
French MMO. Was apparently quite popular but doesn't exist any more (closed in 2014).

Game Design
3D.

Gameplay
Increase your horse skills to go through obstacles (river, mountain). As a point, there is a pay-wall, as your horse is really hard to train without pay.

Two locations:
 * Irish lakes, with lots of mountains
 * American canyons, only available with the USA pass (a real card that comes with the physical CD)

New horses were relased in 2009 (or 2010 ?), only purchasable with real money.

Collectible cards
There is a Mission Equitation Online collectible cards. 170 real cards to collect, split into 6 categories: Breed, Coat, Tacks, Care, Food, Special (+ the USA pass + Silver Star member card). Cards gave advantages in games (new horses).

With the physical box, you get 4 (original box) or 6 (Real Stories box) random card boosters (at least one of each category).

Box
Physical box is still purchasable on some online websites, but the game is no more playable as the servers closed.

Inspiration
The MMO format with collectible cards was inspired by Téléfoot - World of Soccer.
