now a good 1+ years old, this latest trade/fight/explore 1st person POV/cockpit (yes, with mods, though i admit to preferring the default presentation, where the nose of the ship is visible onscreen but there are no cockpit bars obscuring the view or the onscreen hud) space sim is probably the best of the genre now, in terms of polish, depth, graphics, and current generation production values.
(script and mod forum, to see what greatness is out there from the community)
i am running the 2.5 version of the game, with both DDTC mod (adds new ships, stations, missions, sector backgrounds), Cmod3 (a combat mod that overhauls the combat in the game, though i can't tell you how at this point), and a few cheat scripts.
the game is stable, runs well, and looks fantastic. and for those who have been put off by the ponderous, trade-centric aspect of the prior x games, this one allows the player to quite easily play as a fighter, earning credits through combat, so there's no need to slog through the game as a lowly freighter pilot. the combat is pretty great, imo.
x3:tc is likely the best cockpit-based space sim we're going to see for a while (until infinity, whenever that comes out, and jumpgate, which doesn't even allow for a cockpit-based pov yet, as far as i know, and which is online only), so give it a look.
ps- yeah, piper, i'm talkin' to you :-)
