I feel dirty to admit it, but I've been playing Spellfall.
It has everything that is bad about F2P. £70 item purchases, pay-to-revive if you get killed, "rune slots" on each item that cost ridiculous amounts to populate and have to be re-bought if you get a new item, just about every price in the game is geared towards the fraction-of-a-percent of 'whales' that will burn through their parents' credit card to avoid waiting five minutes for this or that.
And yet, I like it. I bloodymindedly learned all the systems and the best ways to game them. That and you can mess with the date to get everything in the game and outrageous amounts of gold without having to bollocks about.
The actual moment to moment gameplay is pretty fun. Honest.
