Actually I would love to see something like that too, however devil may cry, onimusha may be a bit too much, starter kits are supposed to be simple and easy to understand.
However a simple hack and slash game (specially one in 3d, since is really too easy in 2d) could be a great starter kit for all kind of projects. RPG, Adventure, Beat em up, even fighting games.
All we need is a character walking in an eternal plain and beating another single character (a giant ant per example) if the guy has two attacks (fast, strong) that would be enough code to add any number of attacks. and with just 2 characters (minion, boss) we could have a large number of enemies.
