Is it just me or does AC4 gets boring over time? I mean attacking and boarding every ship is the same process, and with a fully upgraded ship incl. elite ram, hull and mortar taking any ship takes about 2/3 hits, and then there's the same old process to board the ship, I have enough money and nowhere to spend it(60k+), the land missions are same, absolutely same as I mentioned before, I had the energy for the first 30-40 hrs, now that I have already become stronger than all the ships in the entire sea(minus legendary ships one of which is already down).
The game seems more like a chore rather than exciting, and this is coming from a guy who spend over 600hrs or even more on Fallout 3 and NV separately, there are so many random choices and events that take place in those games, even Witcher 2 had variation with two distinct story lines, but AC4 has become boring with time, right now I don't even care anymore, randomly attacking man-o-wars/frigates when I feel like it, already have enough metal/wood/cloth etc, gotten through most of the treasures.
Life at sea can become boring, specially if you played like me and tried to achieve 100% completion, even before sequence 5 which I believe is not even halfway of the game I have a fully upgraded ship minus a few elite upgrades, all but 2 forts destroyed, naval missions almost all done, same with contracts, and the challenge is completely gone.
One of the biggest gripes I have with the game is when upgrading ship the appearance do not change at all, for the love of the lord, when we spend hours gathering money and stuff to upgrade a ship at least change its appearance a bit, you can change the sail colors but that's it. Also the hometown(great inagua) is completely useless, there is no reason for me to ever go back there anymore or upgrade it. I'll just finish the rest of the main missions and be done with it. And then get back to Fallout 3
AC4 felt great when I started it, first game to portray piracy in a grand manner and accurate to somewhat, but it quickly turn boring and repetitive.
