It seemed impossibly hard to drive at the time, but driving it 10 years
later, seemed ridiculously easy.
No multiplayer, but the AI was surprisingly good.
It simulated the '89 race, with all 33 drivers and 3 marques (Penske, Lola
and March), and each car handled differently.
Turbo boost was a wonderful strategic choice, but if you ran with low boost,
you could only eliminate 1 pitstop in 500 miles; not enuf to make up the
time lost.
I turned what I thought was a record-breaking 242-mph lap, but Dave Kaemmer
told me somebody else had gone 244 by using a trick I hadn't thought of:
varying the wing angle during the lap (thus increasing grip in the corners
and reducing drag on the straights).
Watching other cars race (a random number seed--like Doppler FX, a Papyt
first--made every race different) was so mesmerizing that I used to park at
the pit entrance or down in Turn 1 and just watch the AIs race by
themselves.
There was no pit-lane speed limit in those days, so you could come off Turn
4 at full chat, slam on the brakes at just the right moment (no brake
lock-up either), and slide to a stop in your pit (the location never
changed) within a foot or two from 200+ mph, and save up to 20 sec. over the
AIs.
Great game (as I said in a review in Car and Driver...also a first).
