It's not your legal (i.e. Shar'ee) duty if you have no savings

Of course not!
Perhaps you are referring to a ruling about painting the picture of a living animal or human being, or making their statues which was forbidden before.
The criterion for this forbidding is that the Arabs, because of their closeness to the time of ignorance, although converted to Islam, had a heartfelt interest in idolatry and preserved their ancestors' works. The Prophet, therefore, strongly prohibited the making of faces and icons to eradicate disbelief and defended monotheism.

So we can conclude that playing those games is not Haram unless another thing comes up, say for example the characters are naked or...

According to Fiqh i.e. jurisprudence, a boy has no need to acquire the consent of either of parents, so he can marry any girl even if it is against his parents' consent.
Please bear in mind that I'm not answering according to moral and sociological advice!
As for the second part of your question, we have nothing like that in Islam and as soon as a person dies his/her connection to their possessions is removed and the properties automatically go into the account of the heirs, so if one is going to deprive an heir of getting their properties, they must transfer whatever they have in their lifetime to other people.

You need to wait till the 3rd starts and as soon as it starts the Iddah period is over.

Hadith n. 312

312. Amir al-mu'minin, peace be upon him, said: Sometimes the hearts move forward and sometimes they move backward. When they move forward get them to perform the optionals (as well), but when they move backward keep them confined to obligatories only.

312. وقال علی عليه السلام : إِنَّ لِلْقُلُوبِ إقْبَالاً وَإِدْبَاراً فَإِذَا أَقْبَلَتْ فَاحْمِلُوهَا عَلَى النَّوَافِلِ، وَإذَا أَدْبَرَتْ فَاقْتَصِرُوا بِهَا عَلَى الْفَرَائِضِ.

In such situations, the only way that remains is doing temporary marriage.
Resisting this desire is not easy at all.
That's why in Islam there are two types of marriage.
Although the permanent is the best, the temporary is prescribed for those who can't afford and are not able to do it permanently

A very good related answer is as follows:

Sheikh Mufid (r.a) and Ibn Shahr Ashoub (r.a) have only recorded one son for Imam Reza(a.s) and he is Imam Muhammad al-Taqi al-Jawad (a.s) but some other historians have recorded five sons and a daughter for him.
As for Imam Jawad (a.s) the sons are Imam Ali al-Naqi al-Hadi(a.s) and Musa al-mubarqa' who is buried in Qom( Chehel Akhtaran) and he also had a daughter named Hakimah Khatoon who is buried in Samerra,Iraq.

The number is not mentioned, but in fact, if it's like a bunch of hair then prayer in these clothes should be avoided.
see:
Question: Does cat hair affect ones prayers?
Answer: If there is a few cat hairs (one to three) on a person's body or cloth, his prayer is in order but if there are more than that, his prayer becomes void, as an obligatory precaution.

Salaam
According to Sayyid Sistani(may Allah lengthen his life) if one doesn't have a fixed job and a regular salary, he must take into account whatever he acquires for a year and if it doesn't get spent in his year's expenses, he should give one-fifth of it as Khums. So it's going to be a distinct "Khumsi Year" for each belonging, possession or finance you may get.
