I played my first solo against Azathoth because I find him to be the easiest. Sure, you die if the doom tokens get to 14, but after while you experience more monster surges and no gate placements once you start sealing gates.
Anyway, I played Darrell Simmons, who's my favorite so far, pretty balanced. I was doing pretty well at the start, got a weapon, some spells, and an ally really early in the game. However, the terror track was giving me hell from the beginning. With the monster limit only 4, and so many gates, monster surges kept happening, throwing monsters in the outskirts constantly. It was hard to fight monsters and close gates by myself, especially in the period in the Otherworlds where I couldn't do anything about it. It ended up reaching 8.
Also, I cheated once.
I'm sure people can understand this, as a noobie player haha, but I drew the first rumor, struggled to close it out by myself, which ended up setting back my game tremendously. Toward the end I got a second rumor, and cried a little before I drew another card....
Rumors suck.
I went insane twice, but I ended up sealing my last gate as doom token track was nearly full. Thanks to an elder sign and my little cheat that is. :I Next time I don't think I'll go as 'easy' on myself as I did. But it was still a ton of fun!
