If you just want to donate to the cause, maybe you can try buying the bundle in humble bundle. They released an ukraine bundle for $40, with 80+ games and other softwares. You can always pay for a lower price, but you wont get any games from that.
Ps: not sure if this is allowed, but if it is not m, do let me know and i'll remove this post.
no problem! I'm not sure which genre you are interested in, but the bundle also has some old games, like spyro and fable anniversary for example.
Most games that are offered have positive rating, so you should be able to enjoy some of them. From those games, i personally have played and enjoyed Brothers - A Tale of Two Sons. It has a good story and a unique single-player "co-op" gameplay (you control 2 characters in one joystick/keyboard).
