I've just started The Dig which I fell in love with immediately. I've taken a little 20 year hiatus on adventure games but have got back into them this year.
Being an old time-starved patient gamer, I very happily keep a walkthrough tab open for whenever I fancy it. Highly recommended if you want to experience some classic games to the end but skip the frustrations and wasted evenings.
I've been playing Star Wars: Supremacy (Rebellion for US folks) every year since release so 25 years-ish.
Clocked it many times but never played as Imperials, so never even seen half the game!
