I want to play with real people... I could play with bot for free...
You think that nothing to worry? They just steal your money with this bots. They must notice that you play with bots.
If you choose play in the online, you may never know your player is a real people or just a bot. Lots of game don't need more than two people to play.
Yes that's true but unfortunately how can you be sure when it's up to online play?
