I have the strong feeling, that @Jaicee might actually know this (I only know it after googling, which feels like cheating, so I don't say anything).

#45
This turn based tactics on a hexgrid game is supported for more than ten years now with updates, extension and new campaigns.

Doi, it's Night in the Woods.

#47 Hint:

Fly Port me to the Moon. Let me SPAAAACEE!!! amoung the stars. Let me see what SPAAAACCEEE!!! Is like on SPAAAAAAAAAAAAAAAACEEEE!!!

Not sure what game that is, but you've peaked my interest.

45. a. Some say the protagonist of this game is actually the villain, because he wants to destroy the fantasy world in order to go home.
b.  This sequel game allows your characters to be different races.  The first game did not include different races.
c. A GBA game.

43. According to the protagonist of this game,  "_________ is light!"

It's Battle for Wesnoth, as Ka-pi guessed. And in addition to all I said it is also completely free, so you can give it a try whenever you like: http://wesnoth.org/

also at Steam: https://store.steampowered.com/app/599390/Battle_for_Wesnoth/

Correct!

Just so I can stay a few days ahead, here's the next set of hints for my list.

#45

-The galaxy is at peace

#44

-From an island in the first, to the city in this one.

#43

-The fifth entry in this fighting game series revolving around the exploits of one of the most dysfunctional families in video game history.

#42

-At the start of the game the prince of the kingdom orchestrates the slaughter of the main characters military and blames it on a neighboring nation

#41

-A geohound is hired to protect a songstress and escort her to a church ceremony

*watches trailer*

HOLYCRAPTHATLOOKSAMAZING!!!

Nice that you like the look of it. I am a bit surprised, as the game is already a bit old, but if you liked the look and don't fear turn-based at part very difficult tactical choices, then give it a try, as I said it is free.

My #50 and 49 are still unguessed!  Here are more hints

#50: a) I'm a Man, I'm the third. In one particular country I'm stone, in the others I'm giant. Either way, I look the same.

b) I have to beat 8 other "Man", each with a level of their own.

#49: a) It's a movie adaptation that is not GoldenEye 007

b) tutututututututuuuu, tutututututututuuuu, TU-TU-TUUUUUUUUUUUUU, TU-TU-TUUUUUUUUUU, TU-TU-TUUUUUUUUU, TUTU! (Yeah it's the main theme)

#48: Usually overshadowed by his uncle, the main character of this game finally gets in the title for once. ||| Diddy Kong Racing

#47: But #48's uncle always finds a way to come back ||| Donkey Kong Country Returns

#46: The main characters have to find food to bring back to their planet. ||| Pikmin 3
