Most hated gaming misconceptions

[BumblebeeCody]

I usually find that the Pokemon one is someone trying to insult you rather than actually make a false claim on it.
Something like "Pokemon is pretty easy, all you have to do is get level 100 and win". As you pointed out it's really not, it's incredibly in-depth with EV and IV training. Getting to level 100 is pointless now and has been since Ruby and Sapphire started EV/IV training.

I think any game that has a community that is in-depth with their game but not on the scale of bigger games.
Such as:
Devil May Cry/Bayonetta being a hack 'n' slash or mash X fest:
(Just as in-depth as any fighting game. Controls take a very long time to master. See Combo videos/Truestyle tournaments)
Resident Evil Mercenaries: Also another in-depth system that has some fierce competition (Even understand hit/hurt boxes and understand animation frames)

Common misconception:
Xbox LIVE is mostly a peer-to-peer network and not server based. (How much is Gold again now)?

Insert BS about what games are hardcore.
