The first one on my tag is Blue Dragon. I sooooooo thought I would have this completion when I started it. I unfortunately missed 1 or 2 items to get in a limited time area. I didn't have the save to make it easy to get either unfortunately. I do have a save right before a button pressing 5 pt achievement that I thought I would fail and did, but have also never went back to it.
2 was Hexic, never completing it.
3 was Elder Scrolls Oblivion. Finished it.
