Just finished with Darksiders. I'll get into Darksiders II soon. No hurry as I want to get in something else before I do and take a break from hack and slash RPG stuff. l've got Dark Souls PTD edition to play through as well. I should be fine as I like really hard games and have the patience for them. I've played a bit of it and from what I saw it's really no worse than Devil May Cry or Ninja Gaiden despite it's reputation. Most of the difficulty seems to stem from the lack of save points and the fact that you lose power when you die and have to make it back to the point of death to retrieve it.
I'm currently playing Lost and Damned. I finished GTA IV back when it was released, but never played either DLC, now I'm playing through both of them just because. I'm using the latest Icenhancer and a couple of other texture mods like High rez streets and such.
I forgot how funny the game could be. I spent all this time modding it, and about a half hour after starting I ended up sitting my character in front of the television in the game for a couple of hours and watching 'Republican Space Rangers', a PBS style documentary parody, and some Anime parody with a very long winded name. The radio stations have given me a few chuckles here and there as well.
The Simple Native Trainer is a fun toy to add to GTA IV and EFLC as well. It has a ton of options to make things interesting, as well as some major cheats. I'll finish a playthrough before I mess with the game breaking cheats like unlimited ammo or God Mode. I got it for the gravity gun settings, that's been fun to play with.
The Iron Man IV mod is also a lot of fun, but it doesn't work with EFLC as far as I know, I haven't actually tried yet. It's also a game breaking cheat so I'm holding out on trying until I finish both at least once. It's also a huge pain to install, but totally worth it.
