Most of the time I would continuing explore before the battle of hoover dam. Also, really looking forward for Willhaven and Frontier.

I Just go around and harass Legion, White Legs, and the Marked Men before the battle of Hoover Dam. I also like to download the Warzones mod and test my skills there.

Do any undone unmarked quests or side quests, if done download a bunch of quest mods.

I do whatever the hell I want. At that point, I'm so godly OP that I could run around naked and still be perfectly fine so I wear whatever gear I think looks good. I would just kill anyone who was not quest-related. If they were quest related, I'd do the quest if it was worth the experience(not xp, but just experiencing the plot), blow their head off, then eat them. Also, I'd keep collecting trophies to decorate my home.

Trying to pass dls and find Uniques weapons

When I hit level 50, I clean the wasteland by picking up and searching for every item that you are able to pick up in the game until there is nothing left for me to loot.

When I hit lvl 50, I get reborn as a level 1 again. With boobs. Gotta live out the role-playing.

go on a killing spree in all the casinos

When I hit level 50...hm...watch an AlChestBreach video?

No, I'm kidding, I've never made it that far. But now I will, and I'll come back in a month or so to tell you!

Download some quest mods and look for vanilla side-quests i still didn't complete.

Seriously, on FNV I don't know...yet, because I've never reached this level without beeing bored. But now I've installed pretty good GUN mods, we''ll see, I'll try to reproduce the same scheme as FO3

I went to the Capital Wasteland and hunt the Behemoth without companion

Play with gun, armor, and quest mods. Or make a save and then try to kill as many people as you can before you used all your resources.

Create another character since a level 50 character for me is boring because of all your skills and perks making everything easy to beat. Useful for unlocking steam trophies and FNV challenges though.

Wow this topic is very old now, but for everybody still checking on it this is what I did hahahaha

1. Got Vicious Wastes for FNV (FO3 version is so damn good)
2. Took some graphical mods like EVE, NMC, and FNVLod Generator
3. Didn't get WMX anymore (it feels cheaty now)
4. Made my own weapon sfx library with no esp needed
5. Got Mojave Raiders by PushTheWinButton
6. Got Mojave Wildlife by PushTheWinButton
7. No CASM or any save manager mods.
8. Play the game

So now, I have 50+ hours of playtime (still going longer) and thanks to Vicious Wastes, even if I already reached level 50, I can still die from anything. Also, thanks to PushTheWinButton's mods, the game feels like FO3 with the new spawns in the Mojave Wasteland. Now I can encounter mutants and raiders everywhere. Plus, Jackals are really dangerous in my game now.

Try to find more shooty quest mods to keep from completing the the 2nd Hoover dam battle and ending the game.

Providing this means I've completely exhausted all activities such as quests, modded quests, explored every inch and obtained every item, then I'd start all over again

Can't say I've ever hit level 50, think I got close in one of my first playthroughs, back when I was less obsessed with obtaining...The Perfect Modded Game

I would love to reach lvl 50,

But It's incredibly rare I even manage to get a stable working mod list set up, and when I do there's always either that one little problem that bugs me or that mod I want to add that breaks everything

I should probably try to increase my modding capability, especially with The Frontier and New California coming out some point soon.

when i reach lvl 50 i will play main quest, cuz lvl 1-49 just play quest mod,side quest,dlc quest.

i've never hit level 50 from what i remember, since if even the smallest thing goes wrong in a game i restart haha. i imagine if i did hit it i'd restart again though, unless there's a mod floating about that increases the level caps and balances points/perks more?
