My sister is 3 years old. She always plays this game. site is wunderkiddy. This game with paper bird is her favourite. i think he will play this game. link https://wunderkiddy.com/material/where-is-the-bird

Valorant or CS:GO.
If he starts that early, he will be easily a pro later.

Sure, if you want the child to be a Tasmanian devil of profanity in grade school. I personally wouldn't introduce a child of that age to video games but something like Gubble might be okay for someone else's child. Wouldn't mind if GOG released Gubble. :)

My friend's children are always fond of Sonic. I think you should get it for your kid too.

Rayman games looks good or some other platformers or simple racing games

Just ask yourself what you would have liked at 4.
I think at 4 you need games that are not focus on narration and it's better if they are not too difficult, finally a cartoon style is a great way to make it more interesting.

So I would avoid any FPS, Stealth, Strategy and Sport/Racing games... Also if you want to get any RPG or Action they need to be easy to understand. I would also avoid games that are too easy, challenges are great to learn and losing should not be a taboo.

Any adventure game with puzzles is great, any "not impossible" platform is awesome, any really simple RPG should be ok.
A few example:
- GrimFandango is awesome. It's easy to understand how to play, there are some good puzzles that you can enjoy together and the look is awesome and with lot's of colors.
- Asterix&Obelix XXL1-2 are simple action plaform. The story here is not that important. They are not too difficult but they will pose a challenge. And they are cartonish so the style is great and with a lot of colors. It should be fun to enjoy together.
- Evoland 1 is a really simple RPG, should be easy to play even for a 4 years old.

Just remember that kids aren't stupid. They don't need games without any depth, just a guide to teach them what they don't know. No topic should be taboo if well explained.
My suggestions therefore are more general guidelines than hard and fast rules. Even a fps like Duke Nukem 3D clearly not for children if played with the right mood and with the right guide can be fun for a child.
Whether it's a boy or a girl doesn't really matter. Boys and girls are able to have fun with the same things, it's us adults who influence their tastes.

Parenthesis, some things I found funny as a child aren't anymore, but the ones I found funnier still are and who knows why they are those things that made sense. For example I had a video game that taught how to play the piano, I still think it's a lot of fun despite the fact that it's clearly designed for children.
There is simply a huge difference between "aimed at an audience of children" and "made exclusively for children".

The idea shouldn't be to find brainless entertainment, the idea should be to find entertainment that you too find enjoyable but that has more colors and rules that are easy to understand (if you are not there to explain how it works).


PS. My bad I didn't notice it was a post of 2015.

What about Mario or some wooden puzzle toys https://www.toypark.com.au/collections/kids-puzzles

I recommend Yoku's Island, it's a very good game for a child (and for all ages, really).
I'm not sure how a 4-year-old would react to it, that's really young, but I think you could give it a try.
