Well it's almost 19 years old, so 1 hour playtime is still bonkers. Never had more.tham 3 hours on it anyway, i always played on the 333mhz boost, it did kinda drain it faster.
Oh OP, remembered one more to look after: Killzone. Fabtastic isometric shooter with havoc physics. Ragdolls, realistic grenade bounce and some smoke effects that made me go wow in the day
