I'm not necessarily talking about third party add-on kits. It may be an "accessory" in the form of an extra figure, shelving/backdrops, art supplies, flight stands, official "accessories" like Battlemasters, dollhouse furniture -- whatever you count as something extra you bought for something else. For example, I recently got the discounted Selects Star Convoy because of Super Megatron. I don't love the figure. I didn't expect to necessarily. He's there for Super Megatron to stand next to and Super Megatron is something I got because I always liked the design and I actually really liked TR Galvatron. In general, I've noticed a trend with my accessory buying. I used to be very picky about accessories but I bought them to improve or offset figures I wasn't happy with. Something's changed. Now I buy accessories only for figures I really, really like. (I didn't buy gapfillers for Siege Prowl, for example. I like him. I like the IDEA of no hollow plastic in my figures. I kind of thought for awhile that he'd be replaced with another Prowl soon.) I used to try to buy accessories or props to turn a C figure into a solid B. Now I only buy accessories for an A+ figure but I'll mix and match multiple accessory kits. I don't buy a C figure at all and a B figure is, well... It's probably a placeholder. There's no point in upgrading a B figure IMHO because an A is always possible. More obscure characters...? Not even then. Take Repugnus. I think his TR figure is a solid B to B+. I have all three basic head designs because I used to get accessories for figures like that. But now as I look at him, I see the Cyberverse version and I'm pretty convinced that Repugnus is getting a better figure within five years and I probably didn't need three heads for him. Whereas I look at ER Quintessons and I think, "Yeah. Those won't get any better. Time to get accessories and a themed shelf backdrop and start looking into weapons for them."
