Glu gave us Diner Dash, Family Guy, and a slew of vampire-themed RPGs. Their 320x240 titles often featured pre-rendered 3D backgrounds with 2D character sprites, a visual style that aged poorly but was “next-gen” at the time.

Tools:

Eclipse + EclipseME plugin (or IntelliJ with J2ME support)
Sun Java Wireless Toolkit 2.5.2 – The old official emulator.
Proguard – To obfuscate and shrink the JAR.
