I love the atmosphere and gameplay loop in Dragon's Dogma so much, and the way it handles its mechanics, such as character size and weight affecting how much you can carry, make the game feel like it gives you a ton of room to experiment.
Its difficulty is so gear based that getting a new weapon can be the difference between struggling and having an easy time. At first I found myself hating this, since with the dark fantasy setting I thought its gameplay would be just as brutal, but this isn't true. Dragon's Dogma is a power fantasy, through and through. Giving you and your pawn the perfect setup of skills, setting augments, and bringing the right items for any status afflictions can trivialize things. That's not to say there aren't moments where the game can be hard, there certainly are, but nearly every hurdle has some way to handle it in an almost trivial matter, experimenting and finding those ways to "break" the game are just another form of mastery and add to the fun for me.
