Labor Day marks the unofficial end of summer — so this weekend we're previewing the games, movies, musicand more that our staff is most excited about for fall.Below, check out five esports tournaments we can't wait to check out. 

League of Legends World Championship

League of Legends' World Championship may be the most popular esports tournament in the world, featuring the top 16 teams from around the world battling for glory. Six spots remain for two wildcard teams and four squads that make it through their region's qualifiers. If the North American finals were any indication, this is going to be an exciting bracket.

The World Championship playoff will run through the month of October.

Overwatch World Cup

The OverwatchWorld Cup is one of the most unique video game tournaments of the fall, if not of all time. Instead of a competition between self-formed teams, Blizzard's Overwatch World Cup allowed the community to vote on which players would make up the rosters of the 51 participating countries.

Some teams like Sweden and the U.S. are stacked with pro players while some other teams like Brazil have players known more for their YouTube personalities than their skills. The OverwatchWorld Cup will culminate with a live 16-team bracket for the championship at BlizzCon Nov. 4 and 5.

ESL Counter-Strike: Global Offensive Pro League Season 4

ESL's CS:GO Pro League is back for a fourth season featuring 28 of the best teams from around the world. Teams from Europe, North America, South America and Australia are in the midst of a nine-week season to determine qualification and seeding to the playoffs in São Paulo, Brazil. With so many match-ups throughout the season, Pro League is possibly the best CS:GOtournament to determine which teams really are the best. Plus the $750,000 prize pool makes it that much more exciting.

The nine-week season concludes Oct. 13 and the finals wrap up Oct. 28-30.

The Big House 6 (Super Smash Bros.)

Super Smash Bros.can be one of the most heart-pumping, exhilarating and heart-breaking games on the planet. The annual Big House tournament showcases the best-of-the-best in Super Smash Bros. Melee, consistently featuring some of the biggest names in the scene. There is nothing as intimate as a professional Smashtournament in Michigan.

The Big House 6 returns to the Midwest Oct. 7-9.

Rocket League Championship Series Season 2

Rocket League's competitive scene is really starting to ramp up thanks to the developer Psyonix's involvement with setting up major tournaments. RLCS Season 2 was announced just weeks after the Season 1 grand finals with a much bigger prize pool of $250,000.

The tournament is open to any team of three in North America or Europe. Qualifier matches start Sept. 10 and the tournament runs through October and November.
