"But to be fair lets wait until both games are finished." is the best line of all.
Xonotic has many features Red Eclipse does not have, and Red Eclipse has many features Xonotic does not have. Personally I severely prefer Xonotic, and I feel like the gameplay in RE is quite stale compared to the complexity in Xonotic, but well it is far more difficult to map for Xonotic than it is for RE for example.
To be fun, though... someone should post an exact copy of this thread on RE forums but in reverse. Trololololololol.
