Mafia: The City of Lost Heaven - I finally made it not crash at the second mission like it normally did on my PC. It's also hellishly difficult compared to even older GTA games, and surprisingly the biggest source of frustration are not driving missions, but fighting enemies.
The mission "Better Get Used to It" (very ironic name) is incredibly shitty - you and your partner have to kill a whole group of enemies with baseball bats. Unlike even GTA 3 (let alone 4 and 5), the swing animation is veeeeeeeeeeeeeeery slow, and the basic attack does almost no damage. You can knock-out enemies if you charge up your attack by holding LMB and strike them from behind, but the enemies keep circling around and hitting you, interrupting your veeeeeeeeeeeeeeery slow attack animations and leaving you defenceless for a second or so - they can land 3 or 4 attacks at you that way. Whoosh, and 50% of your health is gone. To make things worse, your ally can damage you as well if you're standing near him.
AND THEN you need to shoot a dozen more guys with pistols, and guns here aren't like GTA pistols. They knock off 30-35% of your health in one go, and they also make you flay around defencelessly for a second or so, allowing enemies to land even more hits. Since you've lost most of your health in the previous few minutes, it means instant death. No health pickups are anywhere in that level. If you die, you're sent back to the beginning of the fight. If your buddy dies (and he can easily die as well!) - back to the beginning.
All in all, the controls appear simple enough that I feel like an autistic asshole that doesn't get elementary things, but the whole combat system is actually so clunky, it's unbearable. I'll just use a trainer - this is apparently one of those games which are tough as nails even if you use invincibility cheats.
