State of Decay: YOSE. Should I buy?

They gave it away for free recently (Windows Store version), so probably not.

Absolutely, it's great. $3 is a steal for what it is.

There will be bugs, but in my experience there was nothing game-breaking.

There is no unnofical patch. It has more bugs than the original version which has been disabled from purchase. YOSE is a lazy cashgrab that adds almost nothing to the vanila game, just your worthless preorder bonuses (which is the last one i will ever fall for, RIP my friends money), supply drops that make Breakdown easier, more guns, as if that was needed, and Lifeline characters in Breakdown...and what did it cost? Polish, refinement, style... it introduced SO MANY bugs, it even broke zombie AI, like for example in Lifeline original version, zombies would during the siege, run to the gate instead of climbing over the too high, barbed wire fence. YOSE? Just climb over, anywhere oh and have fun hunting down the last zombie that prevents you from proggressing after a siege if thats even possible since most likely youl just have to restart the game and hope for the best. So many bugs and gltiches (which btw where in the original but got patched out and reintroduced and turned to11 in YOSE). It was a cash grab, i think the only reason it existed was to sell it as a normal game on the xbox console at the time because the game originaly started as a free arcade title i think, it was the best one but they wanted a actual normal release of it as a game and this is what it is but ported to pc with no testing and no fixing, it improves upon NOTHING, it downgrades infact.... you know what Undead Labs did care for tho? Selling T-shirts and abandoning this buggy release to start copy pasting the game with the number 2 put in the title, which is EVEN WORSE than YOSE, believe me, i would make a review comparing both games if i had it just like i did with csgo and css, god i hate csgo. But nyeah, i was one of the idiots who bought it for 26 euros...well...my friend did since i never have any money. It was one of the last games he bought :/ probably saw what a piece of shit it was after i explained to him what a collosoal waste of money it was since i owned the original version with both DLCs. I truly felt like it would add A WHOLE LOT more and i was so stupid wanting those preoder bonuses like ability to order a car in breakdown since in latter levels cars become more scarce... but the game was just so boring and repetetive, and not fun, i wouldnt reach those extremely hard levels... what a waste.... i have 0 confidence in Undead Labs being able to make their dream game with their incompetence, titled, ''Class 4''. The ultimate, bestest zombie survival MMO.

I recently played the game from main story to the DLCs without problems.
I liked the game, the gameplay is nice when you get used to it. If there's bugs in the game then they're not game-breaking.

I missed out on this on the tail end of the Autumn Sale because it ended one day before most of the Autumn Sale discounted games and kicked myself for missing it, and hoped that it would again go on sale again for the Winter Sale.

Not missing out this time around.
