Penumbra in Amnesia

[Tanshaydar]

If it's not for sale and a CS by the same company, why is it illegal? I'm sure he wouldn't sell it, THEN it would be illegal. Just saying basically, make Penumbra as a CS (TC) for Amnesia as Amnesia has much better mechanics. I mean... People already import all the models and whatnot, it'd just basically be like compiling them all in one campaign.

Black Mesa is another story. It is approved and sometimes supported by Valve themselves.
However, remake of Penumbra would cause a lot of problems. Firstly, voice acting and music part cannot be re-done, or if it were to be re-done, it wouldn't be as good as original was. So, it'd likely to cause some bad reputation of original Penumbra games in public, thus affecting the sales.

If it were to be better than Penumbra, then no-one would buy Penumbra but only buy Amnesia and play this re-make for free.

Frictional Games usually takes an attitude where they don't give specific permission, nor take action against it. So it is unlikely that they would take legal action against this project, however it's still not legal (considering all assets in Penumbra are STILL copyrighted property of Frictional Games) and not taking any legal action doesn't change that fact.

Either way, this is a still born project to me.
