"As MaximB has written, LGP is far from dead. We have several ports already underway and we are in talks about several more. I realize our blog has been a bit quiet lately, but that has been at least partially caused by us being busy . I'll try to get something up there soon.
If you have any questions, feel free to ask them here, PM me, join our IRC channel (#lgp on irc.freenode.net) or e-mail me directly: eskild at linuxgamepublishing dot com, and I'll get back to you as soon as I can.

I know what you mean, I'm upgrading the GPU on my dev Xeon workstation (that doubles as my gaming machine), so it'll be able to keep up with major battles (XTM installed) once your empire goes into overdrive. (6 HQ, 10 complexes, ~150 ships).
Try a script called Death Match Arena / Redux. Nothing beats going one on one against a fleet of M1's and M2's surrounded by assortment of M7, M6 and M3 ships.
