I think Skyrim is really one of the best, however I also really enjoyed the Saints Row series. I  really love games where you're a in a gang, and SR4 added superpowers to it, so it was obvious that it was right up my alley. The DLC where Gat goes to Hell is also super fun. The mechanics were good, and I super enjoyed it. 

However, Skyrim is probably my favorite game of all time. Once Mods came to Xbox it gave the game a whole new life. I'm a huge fan and will always vouge for Skyrim.

Honorable Mentions:

Starfield

No Man's Sky 

Cyberpunk

Any Assassins Creed.

Best game is Breath of the Wild. Gives you all kind of freedom, no hand holding, and expansive maps and tons of enemies with puzzles everywhere. Best game, convince me otherwise.

for the last 2-3 weeks its been hours and hours of Skryim, and all the DLC that goes with it. Although I also have to admit that I've modded it out the wazoo as well. 

Its hard to say because there are so many great ones but one that always sticks out in my mind as enjoyable throughout was The Witcher 3 Wild Hunt. Everything in that game was great from the combat to gwent. I happily played that game for well over a year just to beat the base game and the expansions. 

It's probably Morrowind. I don't remember any other game that gave me that feeling of getting immersed in another world, exploring different places and cultures. Really unique from that point of view, other "similar" games weren't so special.

Honestly, a real throwback for me was the Saints Row series, at least Saints Row 2 in particular. That game was top-tier fun and had an alright story, really engaging. Saints Row 3 isn't bad but I wouldn't chalk it up to 2.

As of right now the best game I have played is probably Starfield I have been so sucked in to it.

isn't life just a big ol' game in of itself. I mean we wake up every day and have some sort of new challenge or level to complete. You never know what obstacles you're going to come across and what big boss you will have to defeat at the end. To top it off, you only have one life, one chance to win, so might as well make the best of it. Life is the best game I am currently playing.

Best probably Fortnite early years, I also loved MW2, black ops and loved rust for about 5months was very good game with group untill get offline raided they were greats times but game I've played most is league of legends got really addicted to it and just end up playing it even though hate it lol

the best game iv ever played woud total war rome 2  its fun hope  you all play the game its cool gaming is fun i  like MR lot 

Honestly best game I’ve ever played would have to be the Mass Effect series, it’s technically 3 games so if I had to pick just 1 it would be the 2nd one but the whole series is stellar.

honorable mentions would be:

falliut new vegas

total war Rome 2

stellaris

kenshi

rimworld

darkthrone

It's really hard to say one game 

But I have most hours on Medieval 2 total war.

Then it's prob Fallout 4 right after.

Both modded of course, modding community are better then the creators nowadays.
