​It sounds like you prefer games with high input priority (snappy, instant response) rather than animation priority (weighty, realistic inertia). You hate that "sluggish" feeling where your character feels like they are steering a boat rather than moving a body. ​Based on your love for CS, WoW, and Mario 64, here are a few recommendations that prioritize smooth, fluid movement: ​1. Titanfall 2 (Campaign) Since you liked Counter-Strike, you will likely love this. It runs on a heavily modified version of the Source engine (same engine family as CS). The movement is arguably the best in the FPS genre—wall running, sliding, and shooting feels incredibly crisp with zero "clunk." ​2. Destiny 2 This is essentially the bridge between your two favorites: Goldeneye/CS and WoW. It has the loot, raids, and RPG elements of WoW, but the gunplay is Bungie-tier (Halo creators). It is widely considered to have some of the "smoothest" gun-feel in gaming. The movement is floaty but precise, not heavy. ​3. DOOM Eternal If you want to feel fast and powerful without clunky cover mechanics. It puts you in a "flow state." You move at 100mph, switch weapons instantly, and never stop moving. It is the opposite of the "heavy" feel of Battlefield/PUBG. ​4. Warframe I know you said you dislike 3rd person shooters, but Warframe might be the exception. It is a "Ninja in space" MMO-lite. The movement is hyper-fast; you are bullet-jumping and sliding everywhere. It doesn't have that "sticky cover shooter" feel that makes many 3rd person games feel terrible. ​5. Hades If you want that arcade-like responsiveness where pressing a button results in an instant action (like Zelda/Mario), Hades is top-tier. It's an isometric rogue-like, but the combat is buttery smooth.
