เมื่อก่อนตอนภาค3ออก อีกสักพักก็ประกาศว่าจงรอภาค4สิ้นปี2013 สุดท้ายก็ออกจนได้
เข้าไปส่องดูwebบ่อยๆครับ เห็นว่ารื้อไปมาหลายรอบเลยออกช้า
ผลของการรื้อหลายรอบพยายามจะข้ามภาคเก่าที่ดีมากอยู่แล้ว บวกกับเป็นยุคสมัยของ in app purchase ก็เลยดูเยอะไปครับ โดนอักอะไรก็ไม่รู้มาเยอะมาก ซื้อมาแต่ออกวันแรกแล้วเล่นไปแค่5-6ด่าน รู้สึกเหมือนโดนจับไปสัมนาขายตรงยังไงไม่รู้ ข้อมูลยุบยิบเยอะมากไปน่าเบื่อ ผ่านไปไม่รู้กี่ปี(2016วันที่DSIจะบุกธรรมกาย)ความเอียนค่อยทุเลาลง ขุดเอามาเล่นใหม่
