It's impossible to really condense the concept of gay pride down to any one thing - but it is a generally well-accepted fact that there is often very little choice in the matter of who you are, and who you are attracted to.
What you do get with growing gay pride acceptance is the ability to choose to act on that attraction.
Progress may move slowly, but video games, even big-name AAA games have been stepping up to expand who and what you're allowed to love. You can't make mention of these games without entertaining BioWare's Mass Effect trilogy.
The first two games have always offered the possibility of same-sex relationships, but these were offered regardless of whether you chose to play male!Shep or fem!Shep. And while fans may go into conniptions over the ending of Mass Effect 3, with the introduction of Samantha Traynor and Steve Cortez, this was also the first time in BioWare history that full romances were possible exclusively for same-sex characters.
It is only one step further in the series' long-running dedication to the freedom of player choice.
