Yes, this would be far better.
I really don't understand LEGO trying to get into table top gaming markets, like board games, or with the upcoming Ninjago wave utilizing DnD like aspects, or shoot, even the new Lego Mario. It's a fun gimmick but it's not gonna give lasting results.
I think Lego needs to abandon the hardcore gimmicks and continue their efforts in neat themes with excellent builds. If they're gonna use gimmicks, they should do it sparingly. The Hidden Side theme recently uses a gimmick, but it also has some really cool building techniques. Meanwhile, stuff like Lego Mario will require new electronics and expensive molds. (I personally see it being a financial disaster when it finally releases.)
They could easily make their evergreen themes more interactive like Hidden Side. Make cooler builds for less expensive sets, for example. I remember how amazing 2006-2008 Lego Castle was, with it's high fantasy theme. Lego should return to that in their Lego Castle stuff instead of just doing "uh good clan and bad clan" like they did in Lego Kingdoms.
