Good idea. Make hardcoe mode harder. I still don't see the point of the developers making the game even easier though. Because it's fun and it doesn't detract from the game for those who want hardcoe
Fallout 3 and Oblivion had no important variables that the developers had to worry about to make the game playable after the main quest was finished...Then neither does NV...in FO3 you were dead...if thats not important nothing is.
Also if you really want a difficult experience I can design you a hardcoe mode that would be more to your liking I think. Keep everything as it is but add in...
1. An invisible "heat" monitor on all automatic and energy weapons. Gets to high and the weapon either jams or explodes.
2. Caps have weight.
3. Broken items are gone forever.
4. Addictions are permanent and withdrawals can kill depending on the chem.
5. Explosive ammo has a chance to detonate in your inventory with every critical hit you take in the body or any critical hit at all from incendiary damage.
6. Damage heals at roughly real life tempo.
7. No fast travel at all.
8. No one is fooled by changing "costumes" or at least they get a perception/intelligence test to see through your little ruse.
9. Crippled limbs have a chance to be gone forever (hope your head is down).
10. Once per day (forever) and at random there is a chance that your implants are rejected causing you to pass out. Even in the middle of combat. The chance of rejection gets higher with every implant.
11. Your head takes damage 3 times as fast as your other limbs due to previous trauma.
12. Once hardcoe is chosen there is no going back.
13. All percentage chances for hardcoe mode are variable by difficulty (veryeasy/hardcoe has a different set of percentage chances than veryhard/hardcoe).
I could go on but I think you get the idea. Not everyone wants to play a game for the challenge of it. Only drooling competition junkies would want to eliminate everyone elses fun to promote their own. A great deal of people actually like having the option of stomping through 10 Deathclaw Alpha's and then drinking a Nuka-Cola. Not that everyone will actually do it but there is no reason to take the option away. As I said...make it so that hardcoe mode is just that...and make it so that the game is more like FO3 when hardcoe mode isn't on.
