I only recently joined the online game Howrse and was shocked to discover the amount of money you had to shell out if you wanted to progress!
I have no money and don't want to waste it on a game anyway, so I deleted the account .
Everything in the game costs passes, which you buy with real money, from special coat colours to backgrounds to even just being allowed to change you horses' names . I don't mind subscribing or just being told at the start to pay x amount to play, I would have done that, but sneakily forcing you to pay for things is not on in my book! I won't support people who do it, either.
Club Penguin (all those years, haven't been on in ages) gets you to become a member and you have access to everything, and I actually was allowed to become a member one year as a Christmas present. That way you know exactly how much you're paying, but you only really buy a couple of passes at a time so it's hard to work out exactly how much you've spent. Not to mention that once you progress, you want to keep going more and more so you pay more. Clever marketing, but immoral in my opinion.
So for people thinking of joining Howrse, if you want to do well at all, you're going to need quite a bit of real money to play too.
