Having finished Half Life 2 again last night, this time on hard, am I the only one to think that Hard isn't much more difficult than Normal. I do admit that there are a couple of caveats though. I'm bound to be better at the game since I know what's coming (although you can do that with save and reload), allowing better planning, ammo use etc. Secondly, I find that Deathmatch-honed tactics ("shock and awe", not being stingy with combine balls, superb accuracy with the crossbow) make me play the game in a different way, with "more" success.
My question is, what do you think should be changed to make the hard mode truly hard? I would say:
1. An extra sophistication to the AI e.g. rushing, flanking, co-ordinated attacks
2. Reduced suit power pickups/ammo, but not health
3. Striders earlier in the game - for the cool factor - or be able to engage the ones you see when you hit the streets
