The GDI Refinery
The Refinery creates credits needed for research. Eventually, you will need to build bases with only those things on there. Building, or founding new bases costs a lot of credits compared to Research Points. It just depends how fast you want to reach the maximum amount of bases or just get those researches for attack and defense done a bit faster? Not sure but again, base building isn't my main priority and well, I prefer to have less useless bases. nearing 15,000,000 per hour of global credit production is a lot more than I ever wanted and many have a LOT morethan that, I'm like considered a broke ass almost.
