I'm not trying to be the bad guy here (again) but its like jb says.. It is 2012, every low budget computer/laptop you buy is able to this with ease. So i don't think the modder needs to "lower" his work just to make sure that a few people are able to run it.
The needs of the many outweigh the needs of the few
First of all, there are quite a bit more than just a "few people" here that don't have high-end systems.
Second of all, it's courteous for a modder to include lower res stuff so we can ALL play.
Third of all the "needs of the many outweigh the needs of the few" only goes so far.... and the saddest part is you already know that.
Fourth of all, that you've alluded to the fact that your system is ballsy enough to run BC with everything on very high settings makes me wonder what your system specs are...
And finally, not to completely spam this thread, I'd like to say that the Excelsior has always been my 2nd favorite ship design and with Wiley doing his "high standard" work on this new pack... I'm very much looking forward to it. I love the old pack, I can't even imagine how good this next one will be.
