Most Sierra games were trash though, but they got better later on. Gabriel Knight is probably my favorite from them.
Leisure Suit Larry was my go to growing up, I remember trying really hard to answer the Age Quiz questions and getting stumped with the response “YOU’RE A KID!” Then my mate showed me the CTRL-ALT-X hack and it was on like Donkey Kong.
Police Quest, Space Quest and Kings Quest are all great too.
I don't think you can actually miss critical items in their games, but with the early games it's easy to get stuck.
Maniac Mansion becomes unwinnable if a character carrying a critical item (such as the glowing key) or with a needed ability dies. Or waste the paint remover on anything but the paint blotch.
ZakMcKracken becomes unwinnable for the same reason and if you just throw random needed items into the artifact mailbox in San Francisco. Or return to Earth with the two girls on Mars without doing what you need to do there. Or just running out of money.
You can theoretically get stuck in Indy 3 if you run almost out of health in the castle and can't get past one of the guards (not all can be bribed or talked out of it). There was no cheat button to win fights in Indy 3. Pressing 0 on the numpad in Indy 4 lets you win fight immediately, thank fuck because the fights in 3 were trash.
Nothing compared to Sierra's games though.
PC games to me are as foreign as aliens to me, tbh.
Millennial confirmed.
