1st problem: Okay the heck is the tower game he was playing? I thought it was single player, but it has to be multiplayer. But multiplayer doesn't make sense in the context of him being the only one still playing it. His first major item he gets gathers and fuses skills... The hell are skills? If you are playing a game, do you pick your skills? But this is the real world and people seem to be assigned them like other gate type manhwa series. How can MC know the answer to all different types of fusions (like the contract fusion) if he was the only one still playing this game for YEARS!?! Where can he find other players to take their skills and fuse them? How did he do this testing in the game that was multiplayer, but he was the final player?
2nd problem: his confidence. Is this game virtual reality or a PC game? It seems to be a PC game based on the technology of the world, but it has to be a VR game for his level on confidence. The hell does it come from? Even Kim Dokja acted confident but really struggled to enact his plans because he is an office worker who has never worked out a day in his life. Even with MCs knowledge that doesn't equal skills to back it up. MC knows the attack patterns on the mobs, but if it was a PC game, just cuz you know how to beat a monster in a game doesn't mean you can easily defeat it in real life where it's your body and your muscles you now have to relay on. MC was established as broke, had to fast before large food intake, idk how he has the strength to reasonably accomplish this. Also his cheats make no sense if he was solo-ing this whole thing for the last idk 6 years (ik it's 11 years but I'm assuming there were still some people till about year 5 when the game should mostly be forgotten by now), especially since he had to recreate his character from scratch. That doesn't make sense if his skills are dependant on other players skills to copy and fuse?!?
Problem 3: dumbass side characters. That woman who got stuck in the labyrinth with MC at one chapter is like, we have to stay near him so that we can escape, and then the next chapter is like, help is coming in 3 days, let's kill him now. They still aren't gunna be able to escape.... Sigh. This is brain dead. MC is over confident and has physical skills that come out of his ass (will make sense if there was progression due to stats or something, but he defeated tree monster without any of that...). I just wish I had something else to read. I've read everything by now :')
This is a personal rant, I do appreciate civil discourse about the problems I've pointed out and how you see them differently or if you agree. I'm still gunna read because I eat trash unfortunately, and I've got nothing better to read rn. I'd appreciate recommendations if you got them. I just had to rant since it won't leave my mind till I write it down :/
