15h into the game, haven't died at all so far. People told it'll be harder towards the end but then again the puzzles are keeping the game alive for me. I'd recomend Final Fantasy 4 (was rather hard imo, which kept it interesting.Been a long time when I actually had to stop n farm experience for a boss fight or actually come up with a strategy for the fight.) Final Fantasy 4 Heroes of Light ( *drool* @ the graphics, interesting fighting system, love or hate - game.) Those 2 are what I can recall atm, I'll give you more heads up after a good nights sleep.
Not turned based. @Topic Sands of Destruction SRW: Original Generation Final Fantasy 3, Final Fantasy 4 Black Sigil: Sword of exile (WARNING, do not play this game without "no randon enconter" cheat on!)
Mario & Luigi: Bowser's Inside story...or maybe Partner in Time. Final Fantasy 3 and 4 (I never beat 4, but I did beat 3 before) Golden Sun: Dark Dawn Sonic BrotherHood Digimon World DS or Dusk and Dawn Magical Starsign (It might look girly, but the battle system is pretty cool...The story's stupid tho) Pokemon...If it's too easy play a mod; it's harder and better. *cough* Neo SoulSilver *cough*
