Being a Founder since Season 4 and level 122, I can agree that this game has its perks and flaws so here's my pros:
1) Story: although it's not done yet. The story is satisfying, dialogue is told by text and very few cutscenes. Lovable characters, best moments.
2) Weapons: they're the most satisfying weapons to use and make, some may come to Battle Royale so it's best to use them against the Husk before taking on sweats with em.
Flaws:
1) "Grindy" if you dislike grinding this isn't for you. StW is heavily dependent on grinding to level up Heroes, levels and to go through the story.
2) Convoluted: although the new update gives tips on the game, being a beginning back then, it was hard learning the basics. My best suggestions are to either practice in game and experiment or learn from fellow StW YouTubers like Litanah or DemonJoe.
Conclusion, Save the World is honestly a great game if your willing to dive deep into the grind.
