Well, I went ahead and ordered it. Noticed they had descent 3 + mercs addon there too, if that interests any of you.
If it sucks, well, it won't be the most expensive mistake I've made. Heck, after buying metroid prime echoes, it won't be the most expensive mistake I've made this month. And after catacylsm, ORB and Haegomonia all let me down, I'm not expecting them to recapture the magic of Homeworld, but it looked like a fun, different style of romp.
As for mods, I dunno about this one. Always though Haegomonia would've been nice for that - they had beams, cannons and something that could've been flak. Unfortunately I get the feeling that game was a right royal SOB to mod. Too bad too, as I tend to think most of that game's issues could've been resolved with stat changes.
