This is the best FPS that was ever made in the PC gaming history.
Excellent work, Bethesda. As a casual mainstream console gamer, and loyal diehard fans of Call of Duty, and Ubisoft's user-friendly sandbox action games, I never like Bethesda’s Elder Scroll series or Fallout series, because they lack fantastic action elements, have long dialogue with clunky choices, and are too complicated due to their frustrating attribute and skill system, in which casual gamers don’t know what’s going on in the character level-up mechanism and miss the fantastic gun blazing moments in Call of Duty.
However, from the significant improvement in this title, I can sense the sincere attitude and respect from my newly beloved Bethesda to cater for our taste. This game has improvement because of the following:
1. Removal of annoying skill system, replaced by easy-to-learn perks
2. Addition of Call of Duty FPS mechanics, and introduction of bullet time, both are the best features highly praised by casual FPS gamers
3. Addition of MineCraft base building, another favorite of casual gamers
4. Introduction of a simplified dialogue wheel system, inspired from one of the master piece from BioWare, Dragon Age II
5. Power Armor serves as a cool-looking robot / vehicle, every FPS gamers love vehicle!

6. Best console interface flawlessly ported to PC, even when playing in PC, I can still feel that it is user-friendly, smooth and fantastic which can only be achieved by the perfect harmony of interface from console
Although this game is already the best FPS, as a humble supporter of Bethesda, I would still like to contribute ideas for the upcoming DLC / expansions in future, to further satisfy our gamers’ need:
1. 2-weapon slot only – this is the golden standard of FPS from Call of Duty
2. Removal of action point system, use kill-streak mechanics to activate bullet time, every FPS fans love this for killing hordes of enemies!

3. Introduction of cover-based shooting, TPS mode, with frequent switching between FPS and TPS view, and combat / climbing / cover shifting animation playing all the time – think about Deus Ex Human Revolution, every console gamers love to watch the frequent camera switching with combat animation playing on its own!
4. Removal of weapon mods: please just add the loot-based mechanics from Borderlands, every FPS gamers love to kill enemies / boss for 1000 times or more just to farm the best gear, crafting the best weapon without farming means no fun for FPS fans! ;<
5. Introduction of online auction house: every casual gamers love this feature, and like to use real-world-money rather than in-game currency to buy rare equipment in an open world of MMO!
6. Removal of single player mode, enforcement of always-online authentication mechanism and MMO side quests: quest content in single player is still too complex for causal gamers to comprehend, the best solution is to make the game as a MMO, so every quest can be accepted after hearing 1 sentence of quest details from quest giver
7. Leap of Faith perk, climbing tower to explore map mechanism: the best 2 sandbox feature that has every existed!
8. Reduce the openness of world: please make the world consist of a large set of linear corridors so that player will never get lost OR just mark all the points of interest on the map just like Ubisoft’s awesome Far Cry series
