I'm not a games playing person, but do have some concerns about games that feature in-game purchases. Every so often a news story surfaces about a child who has managed to max out their parents credit card on in-game purchases, often because they don't realise they're paying with real money or don't realise how much of a bill they're racking up. This is fine if the parents can afford it, but many can't and $/£100 would make a big hole in the family finances. I don't know about the prices where you are, but £100 is roughly about what I spend on food for three weeks.
