Meaning

Real Time Attack — the Japanese term for speedrunning, where players try to complete a game as fast as possible in real time.

While the English-speaking world uses 'speedrun,' Japanese communities predominantly use RTA (Real Time Attack), a Japanese-coined English abbreviation. RTA events, modeled after Games Done Quick, have become major community events in Japan. The term covers both casual and competitive speedrunning across all game genres.

2. RTA走者ってほんとにバグの知識がすごいよな。 Speedrunners really have incredible knowledge of glitches.
