Dwight is the man. GoT and SW are probably two of my all time favorite rulesets. GoT is an A+ in my book, with the latest update putting it way over the top of anything else I have played. It just hits all the right notes for me, especially combined with that sweet playfield (I'm a pro guy, but have a great appreciation for the prem/LE as well). SW is a solid A, and with a few tweaks could shoot up to equal GoT. I will acknowledge that both of these games (SW especially) are polarizing though. Those who love them REALLY love them, but there are many who just do not click with them for various reasons.
I never liked GB much, so I honestly haven't given it enough of a chance or taken the time to learn the rules. I do not think I have played it since the update either. I do need to set aside my initial reaction to it and give it a real shot one of these days. From the little bit I have read, it sounds like it's come a long way. I'm just not sure how much I can stomach "who brought the dog?". Ugg...worst part of the movie too.
Munsters I have rarely gotten to play, so I only know bits and pieces. I do know Dwight was tasked with making a more simple, easy to understand game, and from that standpoint I think he nailed it. It has some really interesting things going on, and seems to have some unique scoring strategies. I really love how this game shoots, so I hope he is able to continue to evolve the code and can get enough in there to keep people engaged long term.
As for comparing to BM66, Iron Maiden, GOTG and DP, it's tough because they are all very different games. For me personally, GoT and SW are better than all of those listed, even though I am a big fan of DP, BM66, enjoy what I know of IM, and enjoy GOTG to an extent. Munsters is definitely the shallowest of all of them. GOTG is solid, but about as vanilla as possible, both in playfield and code. It's decent, but we've seen it all before many, many times. DP is amazing all around, and the code is nearly as enjoyable for me as GoT and SW, though very differently structured and not as deep. Super fun though. BM66 is a coding force of nature, and while laid out quite differently than GoT and SW, it does share the similarity of having many different paths and strategies to take. I really enjoy it, but for me personally I find GoT and SW to be slightly better. Maiden I do not know very well, but it is also deep and unique, and is less polarizing overall than Dwight's games.
