(Relics) What is the lowest-development-cost content we'd still find fun?

[Lainmyst]

I get tired of the hate Eureka got. it was by far my favorite content ever in this game. It offered exploration though dangerous, open world area to explore. Can't say that about dungeons or raids. By the time I was finished I had the best summoner weapon in the game. I had some good gear, lots of fun items from mounts to minions, glamors. I got tomes far faster then grinding roulettes every day. Plus it had a good story behind it. Of course it was hard and had some grind to it but no more than any other grind in this game. Not to mention free materia. and I made many millions from it. And I made new friends.
