Thank you for the chance to win Temple of Elemental Evil, Melvinica! +1
I like RPGs because usually they come closest to my ideal game. My ideal game needs to have a memorable story, but a reactive story. The story should always accommodate and acknowledge the actions of the player.
The setting of the story should be believable and cohesive. If the setting of your game is grimdark fantasy, then don't destroy the atmosphere by having a section of the game where the enemies you encounter are the furniture of the room you just entered.
The difficulty of the game should depend on the skill of the character, not on the skill of the player. I always hate games where a new enemy type is introduced and the AI is suddenly brain dead and it's waiting for the player to kill it, just because the developers needed to slowly teach the player the weak points he needs to exploit, for the rest of the game, in order to defeat that type of enemy.
The battles should be turn based. Turn based gameplay allow you to play at your own speed. In the beginning you get to take your time and learn what each spell does and what weakness each enemy has, you explore the interface and read the tool-tips of each option available to you. Eventually when you've gotten used to the flow of the battles you can play much faster, but you would never feel the unnecessary pressure of an unnatural time lime limit.
