In comparison to "unlimited thrill,""new adventurer" and "mercenary legend stage" were not as popular as their game quality was not as good.
"Unlimited thrill" could allow the player to become a low-level explorer and go through many unthinkable missions. Although they could be scary at times and there were already many games regarding explorers, the quality and similarity to reality was striking. There were some explorers who, having tried the game, had remarked that it felt just like their missions in real life, with an 80% accuracy. The remaining 20% difference was that real-life missions were not as scary and life-threatening. If the missions were really so hazardous in reality, sane people would never take up the explorer role. To explain this another way, the name of the game was really apt as it was indeed interesting while being extremely daunting at the same time.
