I've recently become bored of TDU2, for a number of reasons.
-Reliability.
Won't dwell on this, enough has been said before. Corruptions, errors, game crashes etc have all contributed to making it a less pleasant experience.
-Events.
There is no variety at all, once you've done one championship you may as well have done them all, the single player is not engaging in the least.
Earning money (legitimately) is too time consuming and tedious, it feels reminiscent of the XP grinding found in RPG games, and element of gaming I detest. Put simply, there is not a reward that is high enough to keep people thinking it is worth their time.
-Multiplayer.
Seems unfair to judge it given that a good 50% of it doesn't work, that said we shouldn't be in a situation where this is the case.
The community feels.. dull, people just don't seem interested in talking to one another, this though I cannot blame entirely on the game, Xbox Party chat has a fair bit to do with that. Gift and a curse.
-Exploration/Originality
I'm bored of driving around. Ibiza is great and I enjoy it but it is really quite small, Oahu on the other hand is huge but.. I've been playing TDU there for years now and despite the revamp it's really not different enough to make it fun all over again. I appreciate many people are over joyed to see Oahu return and that is fine, I personally would have rather seen another island.
-Damage
Hate it in freeride. It is so annoying, if there was a way to repair it without entering an event or returning to your house fair enough, but there isn't.
A lot of this may seem like trivial crap but I played the hell out of TDU, TDU2 is less than a month old and my motivation to play it has basically dried up. Making it to level 70 doesn't even bother me.
