I have also got a bit bored of the Total war series. BC was a crazy project. I nearly ruined my life on that project. :p FKoC was a much easier and more interesting project. I got to do everything on that one. Thanks for the heads up about TA:TW. Its not really my thing but they put a lot of work into it and it deserves to be tried out.
I've been playing M&B for atleast a year. It seems to bring me back every few months. Though I wonder if my interest will remain now that the beta period is over and updates are less frequent.

My first mini M&B/L&R project that I'd like to work on is the nordic shields. I don't mean offense to whoever made them, but they're really ugly. They are generally too thick plus Vikings had wonderful colourful shields in all maner of patterns. I'd love to make maybe 10 or 12 different viking shields. It would be a lot more interesting to see the nords carry a wide variety of shield patterns than having every man carrying the same shield.
After that perhaps move onto islamic shields for the vaegirs.
Let me know what you think about this idea.
Cheers
