I am an explorer, a pack rat, perfectionist and have grown more of a casual gamer lately. I don't like tediously tough games anymore. (Probably an age thing.)
When the game allows it I explore every crook and cranny of a map. Games like the TES series, Freelancer, the Fallout games (the old ones too), Doom with its secret doors, even old dungeon crawlers (or a more recent one, Grimrock and its sequel), Ultima 7/8, any game that allows me to explorexplorexplore!
In Role Playing Games (or any other game that allows the acquisition of many items, like Terraria) I always walk around with my backpack full of crap, although this is mostly because I never know what item I'll need later. And when that moment comes where I really need to leave behind some stuff, I spend minutes upon minutes to decide what to drop.
I don't blame myself. I played games in the past where I needed to go back long distances in order to find an ordinary item that I dropped due to a full inventory, and a later puzzle required it.
I'm perfectionistic in that when I like a game I need to complete it as much as I can. Collect all the goodies, unlock all stuff.
I don't care about Steam trophies though.
With tediously tough I mostly mean games that punish you for being poor at the game. Like taking 40% of one's money when dying (Hi, Starbound!) or respawning on a spawnpoint and needing to replay 30 minutes of the game again. Those are just mechanics to piss players off and don't add to the difficulty. Very annoying.
I used to play any type of game available, like RPGs, shooters, racing and strategy. Nowadays RPGs are highly favoured by me, as well as those one of a kind gems you sometimes find among indie games. I do play a shooter or strategy game now and then, but I usually end up cheating through them since I lose interest in them.
Might also be the case because they don't make shooters and strategy games like they used to. The C&C series by Westwood and the Homeworld series by Relic were gems. And Doom remains my favourite shooter of all time.
I'm in for a treat soon though. Homeworld and Homeworld 2 are getting a rerelease on the 25th.
