The term “Ameritrash” has some pretty clear negative connotations, although I think of it as a technical term contrasting with Eurogames. Eurogames tend towards abstract play, minimal theming, low randomization, and indirect competition. Ameritrash games tend towards very strong theming, downplayed mechanics, significant randomization, and direct competition.
As someone focused on mechanics in my games, I tend to favor Eurogames and don’t mind the negative connotations of “Ameritrash,” especially having grown up with quite a few board games that were clearly being sold as tie-ins to more popular intellectual properties, with nice theming but the quality you expect from a movie tie-in video game. The Tick: Hip Deep in Evil comes to mind as my personal awakening to horrible, horrible products being sold under the auspices of something popular. (Not that The Tick was that popular, but I liked it.)
Villainous seems to be Ameritrash done well. I have seen some of a game but have yet to play it. A friend who owns it and is also into deep strategy gaming described it as the sort of game you could maybe play once or twice as each villain, but it lacks depth and you will understand everything after a playthrough or two. Not a lot of A Theory of Fun style learning: easy to learn, easy to master. On the other hand, it clearly embraces its theming and embodies it well, with exceedingly high production quality. It may not be mechanically deep, but it does what it sets out to do. It also seems like the sort of game that could have a long stream of expansions (every Disney villain) and be a commercial hit, but I could not tell you how well it is selling. I know it is in mainstream stores like Target, not just game shops.
Do you have games you enjoy that would clearly deserve the label “Ameritrash”?
