Well Met!
I too am on a return-to-gaming trajectory this year, and, like you, Rolemaster just sings to me better than the alternatives. In my case, it is RMSS, but not because I have a strong devotion to it over other RM variants. It is simply what I have. I am, of course, keeping an eye on the RMU development, which I only caught on to recently.
The software efforts caught my attention as well, and they seem promising. Rolemaster, more than most other FRPG systems, benefits from aids that streamline the character development and combat/maneuver handling. Tablets, and networked applications, if well made and well placed, could revolutionize the game play, and could well user in a new ICE era.
I hope to get a campaign up and running, in and around work and other adult responsibilities. My "group" will be a mix of newbies (my sons, some of their friends) and RPG veterans (my friends, and a relative or two). It should be interesting, to say the least.
So, welcome to the forum. I just got here myself, although I created an account ages ago. It is good to know I am not the only prodigal.
Best,
Mike Kelly
