I've noticed a less than enthusiastic reaction to the Titanium assortment, except Optimus Prime. I'd like to lay out the reasons why I will be buying them. - Oddly enough, when Titanium was first released, I wondered what would happen if they mixed it with Transformers. I shrugged it off as a generally impossible idea, but Hasbro seems to think there's something to it. - Since I don't buy many toys anymore, and Hasbro explicitly stated this is a line of collectibles, it's a good way to keep in touch with a brand I love while not going overboard on buying toys. - This is a wonderful chance to buy what are essentially highly detailed statues at a very low price. Even with Star Wars, I've always been very reluctant to buy awesome statues just because of the price. The 6" line is even better, since they are still changeable(their wording). - If you love that Optimus Prime as much as I do, you should buy the smaller ones as well if for no other reason than to invest to insure the line stays alive so we may see more obscure characters and designs. I started collecting the Star Wars ones a couple months ago, and they are extremely hard to find in stores. All I have right now are the ARC-170 and Juggernaut. I regret not buying others when I had the chance. If you do decide to collect Transformers ones like I have, do not pass them up when you see them in stores.
