Knives vs. Police baton? Swing speed (actually matters due to the perk Super Slam), Damage, crit rate, crit damage (the last three matter due to heavy handed), VATS special move (some offer special perks, such as a guarenteed knockdown, higher chance to cripple enemy limbs, or more bonus damage than normal), reach, repair difficulties (repair difficulties actually matters since New Vegas doesn't have draugr wiping their asses with gold coins; money is actually finite in New Vegas)
Light vs. Heavy No it doesn't. The armor cap is around....576? After that, you've hit the cap with 80% damage reduction. Both Light armor and heavy armor are MORE than capable of hitting the cap. As for me assuming everyone's taking all the perks, go look at the light armor or heavy armor tree. Both are very linear (and similar in shape) and if you nerf yourself by not taking all the 20% extra protection perks, you can nerf yourself equally with both.
One handed to Two Handed? This wouldn't be so sad if you were right, but you aren't, which is why Skyrim is so pathetic. Go review their perk trees. The ONLY difference? Two-Handed gets a side-swipe AOE, one-handed let's you dual-wield for higher DPS, or use a shield (which only matters if you get shield perks). That's -literally- it. Two entirely different skill trees and the only difference is side-swipe AOE vs. higher DPS. Same goes for Light armor vs. Heavy, which is basically damage reflect vs. faster stamina regen.
The distance? That's your choice. Both characters can attack from afar if you'd like, both can sneak up if they'd like. The difference is purely in your imagination OR you have to go out of your way to purposefully nerf yourself and MAKE this difference matter. Why should you be expected to nerf yourself?
Swords vs mace - Ok, I concede on the baton/knife. I realised after posting that thy're not the same length. Pehaps a rebar club and a super sledge would've been a better comparison. However, you're complaining about a cosmetic issue rather than anything even remotely game or immersion breaking.
Light armour vs heavy - I'm still yet to hear an argument that hasn't come from a min/max mindset. Come back when you can come up with something that isn't a player created problem.
one handed vs two handed - Are you lagging? There is a definite difference in speed.
Stealth vs stealth - You really don't understand roleplay, do you. If you did, you wouldn't refer to it as nerfing.
This is not a matter of opinion at all. Fallout 3 's world was supremely gamey. A society that failed to rebuild basically anything in 200 some years, "towns" or settlements consisting of two or three people, towns without any visible means of supplying themselves with food and other supplies, little lamplight's children that apparently pop out of the ground every few years to keep things consistent, etc. This isn't even getting into the poor, or downright stupid motivations of various factions you encounter, an aspect I consider extremely important when presenting a believable, logical world.
Uh... yeah it is. In my opinion, FO3 is a better game world than NV. Go on, tell me I'm wrong to have an opinion. And no, I'm not even joking.
That didn't answer any of my questions. Hiroshima and Nagasaki are not wastelands today. You need to demonstrate that nuclear fallout would have effects significant enough to prevent any development for 200 years.
The bombs that fell on Hiroshima and Nagaski were 12-15 and 20-22 kilotons, respectively. The bombs that fell during the great war in FO lore were 200-750 kilotons. Big difference.
But hey, this isn't a debate about which is the better game and why.
