I only found out about this recently.
The “Avenger” Table was built in early 2000, by myself a gamer since 1980, and my father. It’s sole purpose was to make the gaming experience “better.” Long had I sat upon the floor, held on to clipboards, or sat around dining room or coffee tables, and I had always wanted something more. However, I did not have the tons of cash to purchase some large, slick, custom table. Big surprise right? Nor was there anything available via the “open market”.
They sell plans for people interested in duplicating their table.
