Oh boy I hated RPG Maker 2 on PS2. I started with RPG Maker on PS1 which gave me my start years ago. When I got RPG Maker 2 I actually also bought the Prima strategy guide for it cause it was far to difficult to develop for. The engine starts you out with no battle engine. So you have to manually code the battle system in RPG Maker 2 to even get started. How you even do that is explained so vividly in the manual, that it is not even worth it.
So the strategy guide tells you to go into easy mode, go through the process of deleting the annoying sample game in RPG Maker 2 and start making your own stuff. But once you get to know RPG Maker 2 more, you start to see how pointless it is to develop for. Yeah the 3D graphics are cool and the music is somewhat better then the PS1 RPG Maker, but it's just meh. At the time also, I did not own a PC so I couldn't just have downloaded RPG Maker on the PC and used it, made my own games, and released them on the internet. Which would have been nice...
It took me some time to actually want to develop games for RPG Maker again. Because RPG Maker 2 killed it for me. I used to practice so much on the pS1 version that it wasn't even funny. I think a lot of you, if you could have, would've enjoyed the games I made on it if I was actually able to release the damned games online for others to play. But that was an impossibility.
So use the RPG Makers on PC instead. Don't waste your time. Shelve it, admire it, but don't venture into it. It's an empty journey filled with nothing.
