January - Lego Space Systems 453 & 454, Landing Plates & Crater Plates. Best. Modular. Set. Ever.
February - Mighty Max Dragon Island - Just add a blue sheet for water. (Red sheet for lava with the Skull Mountain playset)
March - Robin Hood Sherwood Forest playset - Like the Ewok Village, just better.
April - TMNT Technodrome - Pairs perfectly with Mini Mutants for epic scale!
May - The Family Play Castle - Sadly no commercial for this awesome set. I used to play with this set at my aunt's during the annual Easter get together. I love that trap door!
Fun facts about the different variations at Anne's Odds and Ends.
June - Tim Mee Battle Mountain - Again, no commercial, how sad. A perfect multipurpose playset!
July - Construx 6110 Colossal Set - Very yes!
August - Imaginext Bat Cave - It may be the best bat cave so far!
October - Weeble's Haunted House - This one was a new discovery for me. Found a thrashed set for super cheap! Love that shaky camera work at the end.
November - Filmation's Ghostbusters Ghost Command - Maybe one day I can own one?
December - PeeWee's Playhouse
Did I miss one?
