They can be, if you put effort into it... but I guess you could say there are other methods that could be more effective.?

Nah...

Most games have terrible stories and force them in unituitive ways, many games shouldn't even have lengthy stories, so in that sense I agree. However games can be exceptional story telling tools, The Last of Us, Uncharted, Mass Effect, Final Fantay VII, Bioshock.... Hell even the edlerscrolls series, they don't have amazing plots but they build a rich world just like any novel or TV show through dialogue, music and text

Video games immerse me in a way that no movie ever has. Even games with very basic stories can suck you in at times.

The witness has a terrible story confirmed!

That still doesn't have the same impact as movies can have. Pacing, matching music and directed visuals are important tools for story telling, something that games haven't mastered yet. Sure they can do all that in cut scenes, but you might as well watch a movie.
Games are great at world building, not so great at story delivery. The witcher 3 does a good job at story telling, but most of that is in dialogue and cut scenes, which would have a bigger impact in a coherent movie without the kill, loot, shop cycle interruptions.
I can't interact with these characters at a personal level anyway since the things I actually want to do or say is never presented as an option. The only choice I have is when and in what order I want to consume the story content.

Games can be emotional too on a story level. Ico is still my favorite. Yet it still pales into comparison to what a movie like City of god makes me feel. I feel a deeper emotional connection with movie characters in a 2 hour period, than in 100 hours with any game. It doesn't make games terrible for storytelling, just not as good. Maybe he meant terrible as a story teller as your audience will try everything to sabotage the story.

First of all: Movies are terrible at telling stories. Books are the real master race.
Second of all: Try fitting Final Fantasy X into a 2-3 hour movie. Try TLOU for that matter. They will not have the same impact.
Third of all: Why am I talking about movies?

I agree with him. Books and film are far superior. The best stories in games are the ones you discover yourself while playing such as the audio logs in System Shock/Bioshock/Dead Space or text you find lying about the place. Stories told via cutscenes are stupid and immersion-breaking.

Couldn't disagree with you more. What exactly makes a movie so superior to a game story?

I feel the complete opposite. What breaks the immersion is stopping to pick up those damn audiologs while standing there and listening to them or getting hit by enemies while trying to listen to it.

Lol I like the question mark at the end of the rimshot. As if you weren't sure your joke was funny or not. Tee hee. 

Agreed. I've seen much better stories in video games than through movies. You can really flesh out a story through a 20 hour video game and become part of that story. A 2 hour movie won't do it justice. 

Where I think movies have the advantage is the acting, of course. A live actor can make a good story come alive through expression in ways that video game actors/dialogue almost never do.
