On the Skyrim Vs . F 4 side , it ' s basically whether you want the Nostalgia value and stabbing , or the smooth combat and scifi . Since you liked both of them . I would say F 4 just on the basis that you seem ot be looking for mods , and while Skyrim has a huge library of mods , not that many have been ported over to the Console version yet , whereas F 4 has slowly built up its library over time . Siege , though , that is an odd one to add in . Skyrim and F 4 are both singleplayer explorationheavy RPGs . Siege is a teambased FPS . If you ' re looking for a solo FPS experience something with minimal team interaction like CoD or to a lesser extent Battlefield then Siege is not a game you ' re gonna want . If you like tactical shooters that are very teambased , though , go right on ahead .
