Are there any decent mods out there that enhance the game in a positive way that i should use to make the game better for me. I'm fine with any kind mod.

Like, in looks? or in gameplay? or both?

I hear EVE is pretty cool.

If you want to see how Boone is really supposed to be, use this wonderful mod.
It's simple and doesn't interfere with anything else. It's just a bugfix.

Added: I'm using an Unlimited Companions mod. It's different to have more of them with you...like you're part of a squad. Try this one. After the last patch, I had a problem with the other one and switched to this one and now all seems well.

How does that affect companion perks?

I only have Fallout 3 on PC but these look pretty sweet.

As usual, you get their perk while they are your companion...all of them if you want I guess but I've never tested that. I had 5 once and all 5 perks. I'd like to try that at the battle for the dam though. I've found that 3 is just about right because going through doors can be hairy when they appear on the other side but I'll have 4 on occasion because I have a hard time firing anyone. Right now I have Boone, ED-E and Arcade and their perks.

New Vegas Bounties. I really enjoyed the 1st one.

thanks guy

I recommend only Project Nevada. I've tried other mods but they just go way too over the top in terms of... well, in terms of everything.

I haven't tried Bounties yet, but it sounds a lot like the modder was trying to create a Red Dead Redemption bounty hunting experience where the target's crew chases you after you capture the mark -- which I don't like.
