I purchased the full version of Oregon Trail 5, the purchase key originally worked, but quit working after only a few hours. Then I found out that Gamefools attempted to start billing my account for $14.99/month, which was nowhere authorized in the original purchase (it only showed up on the receipt forwarded to my email). Cancelled the "membership" in time not to get the recurring bill, but still don't have the game and these people are deceptive. Avoid.
