IMO vanilla perk and gun mod systems were Skyrimbad by limiting weapon usage to one good modded . 45 gun for vast swathes of the game . It ' s a combat sandbox with a weapon mod system that theoretically wishes you to use dozens of guns , but perk 3 rifleman obsoletes all handguns and big guns , and a powerful , advanced receiver obsoletes all your other rifles , and rare ammunition compels you to not use your . 50 . Every system in the game is limiting your weapon usage like an asshole . The great thing about Bethesda games is you don ' t need to live with that . Using gun mods adding dozens of guns and console cheats to mod dozens of guns , improved the game a great deal to me . Now it feels like a combat sandbox , where I can use a grenade launcher I barely remember I have , or switch to a SCARH , or switch to Righteous Authority . But you need to know how the game works Modern firearms very popular is totally imbalanced for the first 30 levels , so I didn ' t use the guns . Most other gun mods are fairly wellbalanced and integrated , so I ' d actually recommend maybe not using that one , but using everything else .
