This thread is getting heated in places, let's make sure to cool it down and keep our posts constructive.
Second, the semantics debate over "trilogy" is now over. People have had their say and made their arguments, I don't see anywhere for the discussion to progress to and it's caused enough sparks already.Except that they are seeking monetary damages according to Gamasutra, which I consider more trustworthy in these matters than Gamespot, which probably copied it from Gamasutra without checking it well anyway.
Which is what I've been saying, but Hungry Donner is somehow convinced that they aren't asking for monetary compensation. For now, it is unclear at best.
If the news reports were getting haven't sorted this out yet it may be best to lock this discussion until they have.
I wouldn't be surprised if sueing for damages is a legal 'necissity' like I mentioned later in my post. Without knowing how much they're asking for its difficult to judge the situation. As for legal fees, as Summer points out this is routine and it's part of this being a law suit rather than the actual complaint. Really, if Bethesda wins their case then Interplay should pay for their legal fees, they had several months to settle this out of court and they didn't. If Bethesda looses chances are they'll have to pay for Interplay's legal fees, that's just how it works.
Unlike the FOOL one, the FO1/2/T one will get them bad publicity. On Polish sites, pretty much all comments are now against Bethesda. To an outsider, it looks simply like Bethesda is trying to take away the original games from their makers.
That may be the case, but as others have pointed out if you don't protect your assets it is very easy to loose them. I'd argue the legal system is too black and white in this regard.
If Interplay was required to seek permission for re-releases, and
if they broke this, then Bethesda either takes them to court over it or sets a precedent that they are loose with contractual requirements - which could be used later on other contractual disputes. That's kind of stupid, but it's unfortunately how it works.
