the Dragon Age series (I’m including it as one because otherwise this whole list would just be that??)
the Mass Effect series (ditto)
the Pokemon series (my favourite game so far was probably diamond/pearl because it was the first I ever played :P)
Skyrim: The Elder Scrolls (I just love the open world)
The Sims (don’t judge meeeee I have to have it on here because I have owned and played all of them SO much and every now and then I just get sucked back into it hardcore)
honourable mentions: the Professor Layton series, Age of Mythology, any Lego game
I’m a pretty casual gamer, I tend to prefer things that are just a lot of fun and have an interesting storyline and good characters to an actual like...challenging gaming experience
