There are way too many people who voted "I don't care" and "Yes" in this poll. Timers themselves are ok, but when it causes a death? They make me sick. I love exploring levels and always want as much time as I need to look around. I also hate this feature in arcade racing games. This crap happens even when one ISN'T in last place!
I won't deny, the time limit in the home ports of, say, Virtua Racing is entirely vestigial and probably ought to have been done away with. Still not the strictest time limit in an AM2 game; that probably belongs to Racing Hero, which was arcade-only.
But yes, Security Hall was terrible. Maybe if it had the emerald detection from SADX where you could get alerts for all 3, but like that it was nearly unplayable. What time limit was there in Cannon's Core, though?
In Cannon's Core, you control 5 out of the 6 characters from SA2B in one level and to get the fourth emblem, you have to beat the entire thing in 8 minutes. Like, what the fuck? Anyone who knows what a bitch that level was will understand, although once you get to play as Sonic, you're in the clear.
