a couple game programming questions

I have a couple questions:

1. Is there a better alternative to jMonkeyEngine for creating 3d java games? If so, what are its advantages? If not, is it better to use their supplied IDE or to use something like Netbeans/Eclipse?

2. This is far less important as I may never get around to it, but I'd like to someday make an old fashioned DOS game that would be playable on an extremely old PC. What language(s) would I need to use and what libraries are available for this sort of thing? Are there any good guides on the subject?

Any answers would be much appreciated.

Time to remind javamonkeys about how they suffer:

- no closures
- no lambdas
- no properties
- no templates
- no delegates, events
- no partial classes
- no deterministic finalization
- no LINQ
- no extension methods
- no implicit interface implementations
- no optional parameters
- no adequate memory usage
- no fast applications
- no sane IDE, no standart GUI
- no anonymous data types
- no operator overloading
- no tail call optimizations
- no Silverlight, Windows Forms, WPF, WCF, XNA
