Took me several retries but game finally clicked after I finished Fallout 3 first. Coming from that game, you'll slide right in as there are only slight changes/improvements to gameplay. Desert and cowboys setting isn't really my jam, but glad that there's more variety in the environment as you progress with main game and in the DLCs. There are also multiple endings in base game and DLCs that encourage multiple playthrough (or reload your save game if you're hurrying). Got the "bad" ending trying to please all factions. Will definitely play again someday to try the other faction endings and shoot for other achievements. My biggest complaints so far is that it crashed a lot - even in the middle of combat.
