I have never read Germania ... it's on my list. It's apparently fascinating. Give it a go, and tell us what you think.
There's no doubt that Virgil is harder than Ovid. But it's really not as hard as you might think, and there are lots of commentaries, translations and so forth you can use to help you if you get stuck.
The reason I recommend it is that it is such enormously rewarding poetry, and it is so wonderfully a reminder of why you bothered to learn Latin in the first place. Virgil is completely lost in translation. He becomes wooden, pompous, stilted. In Latin he is subtle, and just unquestionably and indefinably great. Ovid, while a fine poet, is not (in my judgement anyway) on the same level, and not so much lowered in translation.
If you want to try just a little bit of Virgil, have a go at Aeneid II 13-56 (the beginning of the wooden horse story), and then at the death of Laocoon (II 199-249). Skip Sinon's story, or read it in translation. It's classic poetry and a central legend on Western civilisation, well worth reading in the original. It will be slow at first, but it's well worth sticking with. If that whets your appetite for more, you can go back and read the rest of Book II.
