I was wandering: if we already have more games on our site and their contributors and reviewers are unknown and we are looking for them or expect them to report, why not creating a new topic with a list of such games, so guys can look and report back.

I know this has few drawbacks: possibility that someone else gets credits, those reviewers don't come to our site otherwise they would be aware of this and so on.

I just thought that it is possible that those guys reviewd games, come to abandonia but the havent check for their name at the game review once it is up. Well, it's possible, right?

I think the topic you are looking for is:
Games That Need Reviews & Screenshots

Nah, but I think there was a thread for unclaimed reviews somewhere...

Well it happened before, but not very often. There are a few reviews that we don't know who wrote them. The easiest way would be if the reviewer would contact an updater or an admin through PM. Even if they'd just say in a regular (visiting often) I bet the info would be related to someone who could change the name on the main site.
