Any collectors of retired themes here? Decided I wanted to have at least one full collection of a theme and decided on Insectoids. There's a higher number of kits for the theme but it seems pretty unpopular compared to classic space or the early 90s space themes nor does it have anything complicated like a monorail so it seems feasible. With the larger sets I feel like there's too many specialized pieces to just piece it on bricklink but do you guys generally just piece your sets that way or buy them as complete models always?
