BioWare's Mass Effect series is an excellent lesson in character-driven gameplay, a tradition that many fans hope Mass Effect 4 will continue. The road hasn't always been a smooth one, but the majority of players who have played and loved the Mass Effect games are pleased with where its fan-favorite characters have ended up ahead of the next installment. Along with storylines that the developer has shaped, gamers were able to make some momentous decisions for themselves when it came to the fate of the galaxy – something Mass Effect 4 will have to deal with for its own narrative.
