The theory is that Steve D. would organize the terrain sessions. Yes consistent terrain makes sense, but so does hitting the easiest, most common items first.
We need far more terrain that one 4x6 table. It makes more sense in my opinion to figure out what terrain you are making (being consistent in theme when appropriate) ex. trees. Then make enough for several tables and some extras so the store has what it needs for multiple games.
Do the common items like trees, forest templates, raised hills, rough terrain, etc. first then worry about themed items that only fit a limited number of games.
Honestly this entire thread is pretty much BS until someone (Steve said he would) steps up and organizes the club/night, AND a number of people commit to consistent participation.
Until that happens this is all just collective BS.
