I liked the game Operation. I practiced so hard at getting the bones out of the patient without the buzzer going off.
I also liked Girls World which was dolls head with hair that you could style. Mine was a bit different to this one, there was a wheel to turn to make the hair grow so you could have it short or long. 😊
Odin Sphere! You could use a sheep seed anywhere on a level to grow a plant that would drop live sheep once matured, which you'd have to hunt down and slay to create healing potions from their meat. 😶🌫
The question is illogical, as if I remember any game so will so many others of my contemporaries!
Nor was I "obsessed" with any games.
One which seems to have died out, is Marbles, or "Alleys".
It was something like a miniature cross between the English game of bowls and the French game of boule. I do not know if the marbles themselves, coloured glass spheres about 13mm diameter, are even manufactured now.

The girls' contemporay game was "Jacks" (presumably its brand-name), which seemed to involve tossing and catching small metal shapes while timed by the bouncing of a small rubber ball.

Not really games but the metal puzzles packed in cartons of cereals such as cornflakes. The object was to separate and re-assemble two or three pieces of metal rod formed into odd shapes that disguised their basic principle, like that of a key-ring.
Alternative cereal sales-gimmicks were little plastic ship model "kits" of a few parts that clipped together; and little toy submarines. The submarines' conning-towers could be charged with baking-soda to make them delicately submerge and surface in a bowl of water.

"Caps": match-head size dots of what I later learnt was mercury-fulminate, along a narrow roll of thin paper. They explode when struck, and were used in two other long-gone toys, plastic "revolvers" and rocket-shaped "bombs". The latter were charged with a cap under a sprung steel rod in the nose, and when thrown into the air above a hard surface the "rocket" would fall back vertically nose-first, firing the cap on inpact.

Making "dens" - small huts improvised from gaps under bushes, discarded boards and the like.
Making "go-karts" ("soap-box karts" in some parts of the country): four old pram wheels, a central plank, a crude wooden front-axle steered by a loop of rope, a seat fashioned from a small crate or some boards... I wonder how many boys could even perform such simple woodwork now?
