I think square are better.. because it not blizzard who made em^^ so it kinda hi-tech or i dont know how to say.. i mean.. it newest.. and im a little rebel so i like when it a mod.. [like the square..] and it easier to wall
[ya im a waller!] just think about it.. the square fit with your building so put a little Suply wall with bunk and tanks
.. But iso are good too!! lost temple is realy great.. but i prefer the easy way
If you assume that Blizzard didn't make the square tiles, then you seriously should reconsider your view on Starcraft.
