uhh theres a
GW store up in Frisco. I dont like playing there because theres only 3 tables. The emphasis there is on socializing and not the hobby itself so I generally avoid the
GW store.
Hobbytown Plano is on the tollway its a great place to play.
A51 is great as well but its out past DFW airport west of you.
Comic Asylum plano also is a pretty cool place to play on tuesday but its a drive.
Adeptus North Texas is a good way to find games
