Don't know what this is all about. Far Cry 2 was terrible imo. Features =/= a good game. You can have as many features in a game but it's the overall story and execution that puts the cherry on the cake. Far Cry 2 is feature heavy, yes, but it was really one of the more bland titles.
Also you need to consider the generation gap. Far Cry 2 wasn't rushed in an effort to pull as many sales in as possible. Far Cry 2 was made by a group of people who wanted to deliver bold and exciting content to gamers. Far Cry 5 had to meet a deadline.
