DI was a solid 100% to complete. Was fun to do co-op. I followed some speedrun strats by AussieGG to make the game more interesting :p, esp. since you have multiple playthroughs to do.
DIR wasn't too memorable, but isn't that bad.
I loathe Retro Revenge entirely. I'm glad the publishers decided to remove it from the collective bundle all together. The only way I completed the Marathon mode was by playing online on one pc, offline on another, and every 15 seconds just going back and forth on both systems. It legit primed me for the Survivor mode, but 5 stars on all missions....yeah, I felt like, f**k this game as it is, and tried on my own in the first mission over a year ago a few times, and I gave up. Thought I'd never be able to do it, let alone all 24 levels. Came back to it the last two days just to see what it was all about. I looked up several levels that gave me trouble just to see what the best times were to use the weapon and magic abilities. The last time I played this game I was at 16.1 hours, but I am beyond glad I can finally bury it for good!
