I'm generally having fun with the new expansion, but Delirium is absurd. I've managed to beat him a few times, however if you don't have the right combination of items he seems nearly impossible. Some attacks come out of nowhere and give you about .2 seconds to dodge. I wasn't sure if there was a trick I was missing or if he's just a jerk. I can't imagine trying to beat him with The Lost or The Keeper...
The text-to-speech was the best part! Most of my friends gave standard answers, but I role-played which made it way more fun. I got bored of it quickly, though, after everyone left and there was nobody to play with.
I've done it for three years now and the best time I had was with a group of people. If I had to do it alone, I would make a list of games, but not follow a schedule. Play a game until you're bored, then move on.
The hardest part, depending on the time you start, is the last few hours around 3-4 am. I would save a game that's really action-packed to keep your adrenaline up or some form of multiplayer. Good luck!
I'm lucky enough to have a wife that is also in the industry so we play games together with a group of friends a few times a week. A far cry from the days when I was single and would sit and play Skyrim for hours after work, but I'm glad I have people I can still share my hobby with.
As with most people getting older I can't justify those long RPG experiences, but find games with a shorter loop much more enticing.
