You have no excuse now, buy and play this game if you haven't yet, it's really, really good

I found it horrible myself. Tastes differ.

what didn't you like about it?

I have played it on xbox and I liked it, I have played the Solstice game on nes ages ago.
But it was removed, I cannot even buy it anymore there and finish my save.

Well, what did you like about it then? :)

You created a dedicated thread to convince people to buy it (nice price indeed), but please provide some info to back your opinion.

Some reviews mention it is not challenging at all and that most fun comes out of finding secrets, not out of the "main" game itself.

Well, I've got over 140 games on my GOG wishlist, so it would have to be pretty spectacularly amazing to leapfrog ahead of all of those!
