Ever since I built this Kotobukiya Metal Gear Rex, I developed a Mech Addiction, I bought a couple Gunpla to satisfy the urge but then I started to admire Mechs from other Animes and board games. Please give me some suggestions on mechs I really want to collect a vast variety. I already plan on collecting every Metal Gear, and as many Gunpla as my wallet can afford, so there's no need in suggesting those. Suggestions?
