First of all, it's "aggrandizement". Or "aggrandizing".
Second, Mustang is a really exciting pin to play and in my ever so humble opinion, more fun than TWD. I've played both on route a lot (pros) and if I had to buy one at market price right now, I'd buy Mustang. "Easily".
Its tempting to say Mustang could be the next IM (a great game, unloved on release for various reasons). The main reason Mustang won't become the next IM (with its low production) is theme. IMs theme integration (including sounds, sfx and music) is so awesome. Mustang doesn't have all that going for it, but it does play fast and intense with ALOT of risk reward, like IM.
Theme wise Stern kind of whiffed on TWD. Redneck callouts ruin the vibe. And while it makes sense theme wise, there's just too much bashing IMO for a creative pinball. Everything's a freaking bash toy (evidently the LE decided yet a another bash toy was needed as well). Except the clugy crossbow, which might be fun, but I don't know because I haven't played an LE.
