For me, I believe slot games are much better, as they are more entertaining, have less pressure & stress, and gives you the chance to turn small bet into a large chunk of money.
I somehow agree with you, it is all about having fun and making some money while enjoying our spare time. If there was no money factor involved in P2P games, then other alternative platforms may be used. Whenever players play against each other to win rewards which is money in this case, it may go otherwise and cheat issues will appear, IMO. So better stick to the casinos and enjoy spinning slots. Just my 2 cents.
