If a guy paused his video game to text you back, marry him ;)
p/s: Same goes if he was watching TV, movie or doing some stuff in his room. A simple text like, 'I'm doing smtg. TTYL', will be great instead of nothing.
But then, if he chooses to ignore you, don't worry. Never stress about what's gone!!
