Besides, i'm focusing more on gameplay, rather than textures. That's the most essential, ain't it? 
Definitely not. Both go hand-in-hand, though gameplay is way overrated anyways. 
What the....
If half mappers agrees what you say....
Or i should clarify my statement and my thoughts of mapping.I want that map is not fucked up, like; no odd glitches, no void leaks, invisible walls, etc. Then I want that map has good spots to build and does not got huge human/alien advantage. After these are done, then i focus on looks and decorating and same sort stuff.
For me, mapping is fun, but it is also very serious business. Some games depends on good maps. But it is just my personal opinion.

I'm not that unskilled mapper, though these tutorial vids has some material that speeds up my work. Thanks
I first used these curved ones, and then tried these 90 degree bends.... but result is same, so back to these
Idea is, that humans should crawl the pipes, all way down... but it won't work, and trying to smaller them makes pain to enter out... So I'll leave them as they are.
