Really depends on what floats your boat in this collecting world.
For me, the answer is absolutely no. I look at my favorite games that I love to "play" in my collection (Johnny, WOZ, Taxi, RS) and the themes are very *meh* in my eyes.
I owned and loved IM for a long time... honestly, that theme does nothing for me.
I like the game aspect of my pins... theme is really neither here nor there.
