they've been on their last legs for years now. With BIS gone, there was very little of value left at Interplay past its own IP, and most of its better selling games of recent memory were using a D&D license they no longer have access to.
You can thank Titus for this, FWIW, they saddled Interplay (which they own majority control of) with so much debt and so many pisspoor agreements there was no way to salvage the company.
Addendum: I better point out that the above statements are opinions and not meant to influence any investment decision (so as not to get my ass sued). In the interest of fair disclosure I was at one point an investor in Interplay, but have not held the stock in at least 12 months.
