Quoted from o-din:
If there's one thing I've learned since I started collecting is if you have games like this, most people would rather play this kind than a more complicated DMD type game. One of the reasons my DMDs are all gone is they were barely getting played because there were now other options.
That's great if you ideally have guests on a regular basis that actually give a shit about pinball. I'm betting that I'm like most collectors though in that the vast majority (i.e. 99%) of time, guests at my house couldn't care less about looking at a pinball game let alone playing one.
Given this reality (along with space and money restrictions), I've learned the hard way that you should focus on buying what you want to play and you'll get a lot more return on your money as well as pinball enjoyment.
I have a big ball bowler for the other 1% of the time.
