League of Legends is a game that has an immense level of depth and is truly a labor of love by Riot Games. When objectively viewing the game, the mechanics and gameplay are top-tier within the genre and nothing that impacts gameplay is locked behind a paywall. There is an enormous amount of cosmetic options available for players who are looking to invest some money into the game, but all of the gameplay is available for free(albeit, some is locked behind in-game currency that you earn over time). The only negative experience that I've had with the game(which unfortunately happens too often) is that you often feel locked into an unenjoyable game due to the team dynamic. League of Legends is primarily a team-based game(5v5, usually) and this means that when a player leaves or adopts a bad attitude, you are stuck with an unfair game that removes the enjoyment for everybody. This is emphasized by the fact that League of legends games can go on for quite a bit of time(even longer than an hour on some rare occasions). Riot has done its best to address this with a reporting system that has proven effective at squashing toxic players' behavior so that they know to change their actions or even banning those players altogether when they do not change. Due to the enormous player base, however, you will still find people who are going to leave or be offensive and this is what leads so many people to say that League of Legends is a toxic game that robs you of your enjoyment. If you can find a reliable group of friends, though, League of Legends can be some of the most fun you've had in a long time. Regardless, I highly recommend you give it a chance.
