I have really limited time and when I am on half the time I feel guilty because there are so many options and I feel like I am missing out on a lot of them.  What are the D&Ds you think are worthwhile and the minigames that are the best.  Fun counts!

If you're on limit, it really depends on what skill you want xp in since most minigames focus on different skills:
but I like warbands, sinkholes, troll invasion, god statues, tears of guthix for xp and familiarisation for good charms
castle wars is fun if you go to the main world and soul wars was fun before it died

Thank you - I will try those.  I am pretty open for which exp since I kind of bounce around when training.  Most things are good...  Thank you for starting me in a direction!
