Guild Wars, that's the only non-free one with reasonable pricing.
I'd probably play others too if they could decide on one pricing system to use (one time, expensive charge / budget priced/5-15? client + ~10?/month / free client + >10?/month) ... instead of costing like 50-70? for the client, then an additional monthly fee of 30? ... and then full priced expansions and clothing/weapons/skills/character slots/inventory storage you pay another 10? for.
