A videogame for my sister

To the Moon & Ori and the Blind Forest.

Hunnie Pop :B

Deponia is a bad choice. As much as I love the games, they are frustrating at times. Well, the first time through at least. What I would suggest is a decent puzzle game or maybe a rogue-like/lite. I say a rogue game because they are generally played quickly. Rogue Legacy springs to mind as a good choice.

I'm going to have to say Life Is Strange as well. It's story-based, and the gameplay is very easy, mostly walking towards stuff. It looks very good, and the story is great.

My sister has only ever liked one game. Age of Empires. See if your sister might also find it fun.

23 ... hmm ... she can play with me :) I also drop trading cards from time to time :)

First of all I would recommend HearthStone (Blizzard card game). I know bunch of girls which is addicted from this game.
They also have the same age (+-).

And what about Steam games, I could recommend just a couple on my taste: The Binding of Isaac, Don't Starve, Castle Crashers...
You also could play them together online or local coop :)

Also dont forget about Telltale games, she would love it if she like reading or watching TV series.

maybe it is a wii tool, like OhMibod :D

Artifex Mundi's games (hidden objects adventures) are quite good for casual/relaxing gameplay.
I play with my gf at my side and we enjoy them and have fun.
Check them out, there is also a bundle right now on Indie Gala.
Happy holidays!

Before the Echo, Portal, Braid, Contrast, Crayon Physics Deluxe, Flock!, Gray Matter, The Next Big Thing, Prince of Persia, Runaway: A Road Adventure, Tengami, The Talos Principle, Toki Tori, Trine, Unreal Tournament 2004, Velvet Assassin. (:

Terraria

what games she played and liked ?

Hatred

ibb & obb quite good to play together :-)

Girls like Portal :P Well, usually :P My girlfriend for example fell in love with LA Noire. She's not a gamer too, last time she played a game was like 10 years ago and it was The Sims :P She said she likes this game cos story is good, graphics beautiful and it's usually slow as you mainly look for clues and do investigations well, investigations too but I meant interrogations, so it seems much much easier than Portal for example which is easy game too :)

For a 23 year old girl, there is nothing like romance and a knight in shining armor, (if we leave the latter) Deponia series will suit her the best.

Exactly how casual are we talking?
Some of these can be more difficult at end game but I think they're all pretty casual. :s

Telltale Games
Hidden Object Games (Artifex Mundi++)
Skrim/Fallout 3/NV
Terraria
Portal
Binding of Isaac (Rebirth)
Plants Vs Zombies
Rayman Origins/Legends
Toki Tori
Divide by Sheep
Point and Clicks (Deponia, Monkey Island, Cat Lady)
Lego Games
Hatoful Boyfriend (possibly other VNs?)
Pixel Puzzle Games
Child of Light/Valient Hearts

Life is strange, final fantasy, battleblock theatre, south park (if she likes the tv show, is a good an easy game)

Vote for Life is Strange or Wolf Among Us

Thomas was Alone is a cute game, lots of puzzles (in a way) and top of all, an excelent game.

Transistor matches that description perfectly!

Without knowing what she likes and what she doesn't, it's pretty hard to buy her something. What genres does she likes? HOGs? P&Cs? VNs? Puzzles? Platformers? RPGs? Plenty of genres have games which can be considered casual and most of pple will like only some, possibly even hating some others.

Undertale is the most wonderful game I've ever played. Surprised nobody in this thread mentioned it yet.

Life is strange or Child of light

Could you give some examples of games that she like? I gave my sister The Witcher 3 for her birthday, but I guess that does not quite count as casual.
