This year I'm seriously in RPG mode. Currently I'm playing Chronicles of Inotia, The Quest, Diablo 1 (Diablo 2 is next), Rogue Touch and I'm waiting for Zenonia and Wolfenstien RPG. When I beat half of these games I can finally dedicated time to Galaxy on Fire.
I'm playing Persona 4, Rogue Galaxy, Fable 2, Enchanted Arms, and Star Ocean 4 right now. I switch between these games throughout the week.
The fact that your playing many RPGs at once, like myself, do you feel like your sacrificing a certain level of immersion because your hopping from character to character? The feeling comes and goes for me. But overall I'm having lots of fun.
If the story is good enough, it becomes a lot easier. Of course nothing compares to just playing one RPG and really truly immersing yourself in that world and that world alone. Either way I feel really immersed in Rogue Galaxy, Persona 4, and Enchanted Arms. For some reason I can't get into Fable 2 that much, playing it feels like a chore. Only reason I'm bothering beating it is because I paid full price for it. I haven't really gotten into Star Ocean yet, but I've only been playing it for about a week, so we'll see.
For 360: Fable 2, Mass Effect and Fallout 3. For DS: Dragon Quest IV / V, Chrono Trigger, Etrian Odyssey For iPhone: Rogue Touch, waiting on Wolfenstein RPG. I've also been jonesing to play through Secret of Mana again for the SNES, and Final Fantasy VI. I had godly saves in both those games.
