Should games have extra missions after the initial game?

Another question.

There are some games that have certain tasks where the player goes out of their way to achieve a certain feat. An example I can think of is the missions in Sonic Next-Gen, or the Ice Arrows dungeon in Ocarina of Time. Basically, you can skip these in the initial game, and after the game has been completed, you can go back and complete these. Basically, they're extra stuff.

I heard that these extra things can prolong the life of a game, but I feel like that they're either excess padding, or I feel like they are somewhat there to give the player some more things to do after completing the game.

Here's my opinion. Imagine that I'm standing just outside of the door of the very final boss in the game. I like to know that I've completed EVERYTHING, and that this will cap off everything. As soon as I beat this boss, the credits will roll, and the game is officially over. That's how I like it, in all honesty. Some games do this, like the original Super Mario Bros. and Mega Man. I believe that the ORIGINAL Pikmin also does this. Basically, classic games do this. (If anyone hasn't figured it out, I don't play that many modern games. I'm a classic gamer.)

Anyways, back on topic. Do you actually like having these extra side missions to do after the game is complete, or do you want the game to be officially over once the credits role?

Depends entirely on the missions, if it just more fetch quests from point A to point B then I rather they don't include those. On the other hand, if it's mission like those in most role playing games where they include super bosses after completion then I'm all for these types of side quests.

Depends on the missions and/or the game. It can be nice to have but I don't think that it's something that either should or shouldn't be.

Divine Sword and Archangel are right. Here's another answer to that question based on one's personality. Aside from challenging secret bosses, I love side quest that gives a bit more info on the world of the game, some teaser or foreshadowing for its next series. I hate side quest in which you will grind for so long just to get or release the full potential of a certain item.

Well, I prefer if a game is straight-forward. ^_^

This. Completely agree with it.

Yes, that's always what I want from pretty much all my games.

some of the games had really good side missions after the main story was completed , like witcher 3, skyrim etc, but they shouldn't be boring and ridiculous like in ac unity , far cry 4.
