About Rusty Lake Hotel - I guess I will change the description to "Star system for accomplishments" since those ARE confirmed even though we are still not sure if these are the same as achievements. "Confirmation needed" sounds more as if nothing might happen as well and any kind of "achievemenst" might be completel absent.
And one new entry from myself:
Superliminal.
Agree & Thank you. :-)
I will keep it mostly for "strict" entries regarding in-game achievements.
While "researching" i found evidence to a couple of games that have this sort of progress system.
I skipped them, because they were not exactly the "private" version of those trophies that you can mention in galaxy or your user profile.
For upcoming entries i will consider them (for list them here) but will describe them, so that you can evaluate if they belong to the list or not.
Also: 158 entries so far - Yay. :-)
