My boyfriend completely ignores me and prefer playing videogames?

we’ve been together for a year and a half. He completely ignores me while playing videogames and he doesn’t even see my messages. He even turned off his phone and was gone for like 7 hours just to play videogames. Now this time I sent him a message and he didn’t even see it.
I know he likes videogames and have fun but why he can’t even reply to a text for 7 hours? he doesn’t stop playing for a bit? This makes me wonder if I’m less worthy than a videogame or I don't know. Is it too much effort to reply to a message? I even called him but literally turns off his phone and didn’t even care what happens to me.
When I tell him this attitude bothers me he says I’m “way too clingy” but I don’t think I’m clingy? I just want my text and calls replied after 7 hours straight.
