Do you mean like 2'x2' boards or plastic tiles? While I love the look of a beautifully finished table, alone or made of boards...I've never put some together. I need to carry all of my games in my car, so I still to terrain places on various mats.
I'd consider it for maybe a really hectic urban table? I do think it would stand a serious chance of becoming stale though unless you had a large number of boards w/ numerous ways to join them.
