Big Brother Stars is based on the uk version of big brother. Unfortunately, people in there have gotten the wrong idea on how to "play" the game.
In the rookies game, you need to make alliances and vote people out in groups in order to progress in the game, otherwise you don't have much of a chance. It's a little bit similar in the casting games although not to the same extent. The reason people nominate tactically in those games is so they can evict people who post lots because those people are more likely to win, therefore stealing the prize from them.
The stars game wasn't made for that though. The best way to suceed in the stars game is to be entertaining and for the public to like you. People's past records in games doesn't matter since getting far in those games is a completely different skill to getting far in stars. It's like somebody being employed as an IT technician because they're good at woodwork, it's a completely different skill.
The people in the stars game don't seem to understand this though and as a result the 2 people up for eviction are the people who have mostly polled 1st and 2nd place in past games. This shows that over half of the people in that game just don't get this.
So what do the people need to nominate based on? The public will never let somebody they don't like win and the people they don't like will not get far. Remember that the public are voting based on who their favourite and least favourite is from the nominees so nominating people who might possibly win is never going to get rid of the favourite to win. You should nomininate people who you don't like in the game. The public will be seeing the same as you are seeing and will most likely follow you and proceed to evict this person.
If you are somebody who watched the UK big brother and the US big brother for at least a series each, you will understand what i mean by this. There are a few people over the 9 years in uk big brother who've tried playing tactically and those people have never won. The winners have always been the people the public like the most.
The difference is though in real life in bbuk no one knows the housemates and u have to get to like them. Everyone with high karma int his game already has their friends, that are going to constantly vote for them.
But then there's celebrity big brother where they all have fans and they still don't properly play the game. Even if they have their friends, that still leaves even less reason to play the game because nominating the people with lots of friends won't result in them getting evicted.
