For FPS games (CS2, Valorant, PUBG): 5-6 buttons are plenty. Left click, right click, scroll wheel click, and 2-3 programmable side buttons for push-to-talk, scope toggle, etc. The G Pro X Superlight's 5-button design is ideal. For Battle Royale and Shooters (Apex, Fortnite): 7-9 buttons recommended. Side buttons for building macros, pinging, or weapon swaps. Basilisk V3 Pro's 11 buttons give ample options. For MMO games (WoW, FFXIV, Path of Exile): 12-20 buttons ideal for ability rotations. Redragon M908's 20 buttons with 12 side thumb buttons is the gold standard at this price. For RTS/MOBA (Dota 2, StarCraft): 8-12 buttons for items, abilities, and orders. Basilisk V3 Pro or M908 suit this category well.
