GTA constantly evolves and improves, and its writing is always getting better. Its only "downside" is that at times it stops making a joke out of itself, but that's only a problem to the hypocrites who at one time are asking for a deeper story only to turn around and complain that the game is taking itself too seriously once it gets some depth. GTAIV was great in all areas, even if they had to cut out a lot of gameplay (they subsequently included almost ALL of it back through DLC) and GTAV was a massive improvement in every regard. Rockstar "gets" their games, and they "get" their audience, and they "get" how to make widely popular games without alienating their fans. Bethesda can't compare to this track record. They're just chasing the dragon, oblivious to the nature of the beast that is game design, or even marketing and sales.
Despite endless retries and checkpoints making the so-called "suicidal" mission in GTAV a very doable challenge, the game presented a situation that GENUINELY made me extremely worried for my protagonists, and that can be attributed to the game's stellar writing. Likewise, no matter what my choices are, I always feel the weight of my decisions when I make them in GTAIV. I NEVER once dreaded that something bad might happen to James like I dreaded the outcome of Michael or Trevor's actions. I was NEVER worried about Project Purity like I was worried about Niko or Claude getting his revenge! Despite them all being games, there's a quality in Rockstar's work that gets you INVESTED in the world they build, and the characters living in them, and Bethesda
can't touch that, much less replicate it.
