Well, that's a lot of questions, but good ones so let's go:

• Citizens were not allowed to be tortured under Roman law, and the primary victims of torture seem to have been POWs, so then it would be the military unit in charge of them administering whatever punishment was deemed acceptable but perhaps someone else can fill in here, as I am a bit vague on Roman torture practices.

• Ice/snow was generally taken from mountaintops and used for mainly culinary and medicinal purposes.

• The priesthood being unethical, or using their position for personal gain was very common as it was a deeplyCaesa political position. However, as priests were likely to be selected due to nepotism/favoritism, and how influential their family was, priests were more likely to act on the behalf of their families/affiliations, than purely greed.

• Caesar may have had epilepsy (he definitely suffered from some fairly serious condition), but this is only one theory among many, some of his symptoms and their onset are inconsistent with modern understanding of epilepsy and as epileptics were often thought to be divinely influenced it makes sense that this is the explanation that would circulate. As there is no possibility of epilepsy or accurately assessing his family history no one can really say for sure.

• Drugs such as opium, hemp, and cannabis were known back then, but it is hard to assess their popularity, and it likely varied in different times and between classes. These may have been smoked, the leaves chewed or steeped or perhaps mixed in alcoholic beverages. Marcus Aurelius for example was quite fond of opium, one more reason he 's one of the coolest emperors (although both winners and I don't do drugs). Bear in mind however, that the drug use depicted in the show is mostly fictional and for the purposes of drama/plot.

• Not much is known about the board games played in ancient Rome, despite the being frequently mentioned, but one apparently popular one was called "Mercenaries", and was a strategy game perhaps similar to chess, but no-one knows the rules and is the game I personally assume to be being played in the show :-)

• The preferred method of suicide for Roman generals seems to have been falling on ones sword, but many generals/politicians stabbed themselves with knives, cut their wrists, or drank poison.

• Vercingetorix, Marcus Antonius, and Cleopatra were not paraded around the city post-humously. Vercingetorix was marched in Rome on triumph while living, and was likely strangled in his prison afterwards as per custom. Much of the drama surrounding Antony and Cleopatra was rather highly fictionalized, even for a mainstream adaptation, and the events surrounding their suicides and the aftermath diverged from historical accounts. Suffice to say, Antony stabbed himself because he somehow received word that Cleopatra had been captured/committed suicide, but did not die, rather inflicting upon himself a painful, slowly fatal wound in his abdomen. He was carried to her mausoleum where she had taken refuge, and subsequently died, apparently in her arms, whereupon she began cutting her arms, neck and chest (this didn't exactly help her health or appearance). Octavian permitted her to oversee his funerary arrangements and gave her custody of their 3 children with the stipulation she not commit suicide and also cooperate with the occupation of Alexandria, she buried Antony but ended up committing suicide anyway a few weeks later and her son Caesarion returned to bury her, and was later ordered to be killed by Octavian (probably via strangulation).

• Jews occupied a somewhat liminal role in Roman society, they were permitted to practice their religion, but Roman society was pretty xenophobic at the time, and Jews as group were generally not trusted. Severe tensions did exist, namely over the conquest/occupation of Judea, and cultural/ethnic differences, which resulted in riots in many provinces, as well as the series of Roman-Jewish Wars.

• There was some resentment, particularly among the Senate over Octavian's ascension, but bear in mind that that the overwhelming majority of Romans loved Julius Caesar and his assassination was seen as an attack on the common people. Octavian was also very popular after defeating Antony/Cleopatra, and being seen as the successor of the divinely associated Julius Caesar gave him a lot of street-cred. Plus, throughout his career Octavian had a more diplomatic approach to dealing with the Senate and a better rapport with them on the whole.
