I paid money in-game, I usually only do that if I really like the game, though I am having alot of trouble with License2 (3/6) and obviously License1, if you did a L2/L1 assistance function so your friends that already have the L2/L1 Licenses can do it for you and they get a reward for helping you pass your L2/L1 test, sound like a decent suggestion and it helps those that don't have time or are unable to do them. I also have KartRider Drift in my Steam PC Wishlist.
