Haven't read any of the other responses on this thread, but:
How about you find games that are similar to the ones you just listed? (Same category/genre)
Perhaps she may want to stick to the current games as long as she plays it with you
If Minecraft is your main game and adding mod packs would be considered to be an upgrade, then that is good.
You may also consider playing on online servers, or starting your own server with friends, because more people can be fun at times.
However, if one of her main purposes in playing games is to spend time with you, then it would be optimal for you to keep it between you two.
This is if she wants to stick with the current situation.
If she wants to play new games, however, a couple of your suggested games could be applicable.
This includes Terraria as it is kind of similar to Minecraft.
Judging by one of your statements of "literally anything", then any game would be possible. (Something less violent to be honest)
