Splinter Cell Blacklist
SMI Interface in the game is similar to MS Interface in Mass Effect Series which I enjoyed a lot.
Borderlands 2
All the missions are super funny and easy to finish except the Boss Battles which are very much challenging.
Skyrim -Legendary Edition
I finished all the missions of Dark Brotherhood,Thieves Guild,Civil War(I sided with Imperials),Main Quest,Daedric Quests and Side-Missions including Solstein and Hearthfire.
Metro -Last Light
All the levels are having horror genre like aspect which is thrilling to play besides nowadays all the game developers are going open world which would be fun in regard of Metro also which might resemble STALKER series.
STALKER -Shadow of Chernobyl, Call of Pripyat and Clear Sky
All the levels are pretty scary due to mutated animals and atmosphere. While this series ended due to game developer sold to develop MMO type of games is a real loss to the lovers of this genre.
