One thing missing from this discussion: people who in the past bought the game are now required to pay for it again in order to have it ad-free! That's the reason for the big influx of 1 star ratings in the AppStore.

Apparently this isn't actually the case entirely. You can do a restore purchases on the old version now. I haven't tried it myself though.

Edit: remove unrelated edit!

You are correct, it seems a new update was released to allow the restoring of old purchases.

That's good to know. I've stayed away from them because I thought they might be bad ports or something.

Sadly, they are also bad ports. http://www.retronauts.com/?p=3278 They may improve with time, but for now, Sonic is the only playable game in the collection. On the plus side, it is free-with-ads, so you can try before you buy. I think there's promise here, but the current offering is pretty terrible.
