I will probably expand on this in the future, and split it over several different pages.
I grew up with the Sega Mega Drive and never really took well to the transition to 3D games. The 3D games I tend to like are arcade games, especially in genres where the 2D predecessors tried imitating a 3D environment (the clearest example being racing games).
The Castlevania series holds a special place in my heart, especially the non-linear titles featuring Ayami Kojima's dark gouache portraits.
Dawn of Sorrow and Portrait of Ruin for Nintendo DS regrettably ditched Kojima's unique art style in favour of a bland contemporary anime style. Fortunately, there are fans who worked hard to create patches with new artwork based on Kojima's work. You can find these on Romhacking.net
