Not a recommended watching order list, however all shows on this list except for Gundam Unicorn work as standalone.
Planned watch order for Universal Century ("main series") Gundam.
All complete and incomplete series I own.
Incomplete: Inuyasha, Ranma 1/2, 08th ms team, Pokemon, Votoms, Niea Under 7
There. Chii's list is very helpful, but it's hard finding it XD
Animes that just weren't my cup of tea to animes that are just bad period...
