I want to ask about play station games like foot ball games. Is it allowed in Islam? The players, as you know, are like the real ones.

All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.

The mentioned game is not permitted since it contains music, nude pictures, etc. Islam forbids music and all kinds of musical instruments.

Abu Moosa al-Ash’ari narrated that the Prophet said: “From among my followers there will be some people who will consider illegal sexual intercourse, the wearing of silk, the drinking of alcohol and the use of musical instruments, as lawful.” [Al-Bukhari]

The Prophet mentioned musical instruments along with wine, silk and adultery, which are forbidden. There is no doubt about their prohibition. This implies that all kinds of musical instruments are also forbidden.
Moreover, looking at the ‘Awrah (parts of body that must be covered) of other persons is also forbidden. Allah Says (what means): {Tell the believing men to lower their gaze (from looking at forbidden things), and protect their private parts (from illegal sexual acts, etc.). That is purer for them. Verily, Allah is All-Aware of what they do.} [Quran 24: 30]

Therefore, playing and watching such a game is forbidden because it contains many prohibitions.

Allah knows best.
