Looks like Incognito also uses NeoAxis engine. However, in my opinion they both should be published.
The "bad thing" about Wine (which is actually the cause for not including any Wine-using games) is: every new Wine version potentially may break something, and games that worked yesterday may not work any more in the future.
In the case of NeoAxis it's developers (not users) can test every new Wine's version and it's compatibility with the engine; they can also apply their own patches in case of regressions.

Regarding SickBrick, quoting Readme:

WHY ARE YOU USING WINE AND MONO?
In order to run the game we make use of Wine to kickstart our Mono Runtime wrapper which is used on Windows and Mac OSX. Once this is up and running you will find it should not be buggy or leak memory of any kind. Emphasis on the notion that this is not a hack but indeed a genuine attempt to bring SickBrick to Linux in a formidable way.

ARE YOU GOING TO MAKE A NATIVE PORT EVENTUALLY?
Yes. Before we go porting the engine to the various popular Linux distro's we want to test the market with this release. If this begins going someplace and Linux is the place to be we will put fourth the time needed to create a native port of ALL the underlying technology that powers SickBrick Episodes.

So, there is a hope we will get "real" native port some day.

I'm publishing it again for now (at least to let others tell their opinion [otherwise they can't view/comment unpublished game topics]), and waiting for comments.

I think the lack of information about the game being non-native; outside of downloading 300mb file and viewing the README should be an issue, no?

Also, (I say this without snark) there was also hope of us getting a "real" port of Unreal 3.

Cheers,
Venn

Honestly, I'm also not happy with including Win'ed games here. Actually, the real reason I've published it again is the following: what has been seen cannot be unseen what has been published should not be unpublished. Otherwise people who had already seen the game (and maybe even posted links to lgdb page) may say "WTF!? just few minutes ago it was here and now it disappeared". In fact, we should be more careful with publishing the games (no, I don't blame you for publishing them; in this case this was really tricky to understand that it's Wine game - Incoginto news on LGN, no mention about Wine on developers page; in other words, unless you install it and look in it's depths there's no way to realise it's "fake").

Here are few ideas what to do:
* we can unpublish games; instead, create forum topics with the description/links/etc. for these games; apologise to the visitors
* leave the games until database reaches celebratory size of 1000+ games, and then silently unpublish them, while nobody sees.
* leave the games as an exception

>Otherwise people who had already seen the game (and maybe even posted links to lgdb page) may say "WTF!? just few minutes ago it was here and now it disappeared"

Good point, I think the best idea is to silently unpublish/remove them, in addition, I suggest to remove them from the frontpage.

Ouch! it looks like this is already available. I missed the "Shall we record all Open Source game which enter mature phase?" topic.
