Must be that time of year again...
There are casual games and casual gamers and there are hard core games and hard core gamers.
Most games are just games though and most gamers are just gamers.
Sometimes you can play a casual game hard core, sometimes you can play a hard core game casually.
Playing hard core is pretty much defined as spending lots of effort and time. So a game that has a hefty learning curve or takes a lot of time to complete or effort to master would tend to be hard core. The flipside though is that hard core games can often be pretty niche with a few exceptions (mainly from lots of people being trained on prior games, continually building up that segment of players devoted to the specific skill of playing that one game). Often the burnout is high.
Whereas a game that has little depth but lots of breadth (or vise versa) might be pretty easy to pick up and play. Often friends and family can come together to play these game with little effort and a pretty level playing field (mileage can vary with age). The flipside though is that lots of players can put in an exceptional amount of time playing these games (sometimes many times more than a hardcore game) because of ease of picking it up and playing a few rounds of the game. Often the burnout is low.
None of the above _really_ matters. Lots of players have lots of different preferences.
