Quoted from Shapeshifter:I know DI is popular but I agree with Elwin's latest interview that games have got too complex, deep, so only the best players have half a chance of finishing them.
He says 30 minutes maximum to complete a game. Another reason I am looking forward to Maiden
But, a lot of people like these epically deep rulesets so that is cool but they are just not for me.
To me its about the journey, not the destination. Whether a game is deep or relatively shallow, it has to be fun. I have played both shallow and deep games that were a lot of fun and, conversely, there are shallow and deep games that I don't like at all.
I will say that I'm more likely to purchase a deeper game. The games are heavy and a PITA to move around. I keep them for awhile. A fun deeper game keeps my interest longer than a fun shallow game. While I love IM and play it whenever I see it on location, I probably won't buy it for home.
