I kinda feel like there are people that will be better at games over others and seems like the odds of winning arent really in anyones favor, lets say i had a group of 10 people and got them to name a game they are good at, took all 10 games, cut 5 and then hosted a tournament between the 10 people on the 5 games then its clear that 5 people instantly have an advantage, which while if it were just fun it wouldnt matter, but i kinda feel like that £2 could get me a handyj off ryan calvert in the bathrooms and it would be money better spent.

Examples of games i think would be fair and actually fun:
Robot unicorn attack
That TF2 mod is a good call
Super smash bros
something fun like qwop
Tron bikes

Stuff that no one has an advantage on at all in anyway but can still be deemed as competitive
