Linux-Gamers has posted an interview with Croteam about the Linux client of Serious Sam.

How does it come that you have decided to create an Linux port? Do you think that the market for Linux games is big enough?

From the programmer's point of view; with each port you make, the code base becomes more stable and flexible. Source code itself tends to get better and more precisely commented or even refactored if required. Another reason is the power of Serious Engine 2 and Serious Editor 2, everyone should have a chance to experience it. At last but certainly not least, our fans wanted us to make the Linux port and we are very bad at saying no to them.
