@DOBINHO your grammar is really spot on so I wouldn't worry about it too much, and about the whole campaign revamp, It would be good if their were alternate ways of upgrading ships and getting round tech, but think about how hard it will be to code it in. I mean right now cwwallis is busy with OE4 so time and effort is mainly diverted into that current project, but as a later addition, I would fully support it.
@qwaszx147852 that may be so for the early levels, but later you can't turret rush easily, after level 10, you would rely on artillary rushing or cap rushing, due to the AIs gaining phalanxes, faster resource gain, and other buffs.
@caojinyu1985 the OE4 beta is here: http://www.fastswf.com/M09dgBs and currently, no data will be transferred due to OE4 being a completely different game.
@20centimes
you can sell un-needed ships via the shops, also, if you sell ships you can get some much needed ingame currency (not platnum) for beginner upgrades in the upgrade tab of the shop. hopefully this helps
@Voldershort hate to shoot down your idea but, if he reformats those ships it (in my opinion mind you) would kind of ruin the vibe of the upgrade system that the OE3 system has. Also your idea sounds like another space game I've played called Vega Conflict. Just remember, this is just a thought and I do think there should be something else that the ships do if you win or surrender (ex. "warp" away or fly away in one direction")
