I don't have a horse in this fight but this is such flawed logic. DoD has been on the site for significantly longer than MP, of course it's going to have more likes. Just like Bret Favre held almost all the NFL records, good and bad, purely because he played more than everyone else
I don't know how long both games have been here. It's obvious than DoD has more time than MP, that's for sure, but being here for longer doesn't mean a lot if people don't know the game exists or remembers it at all.
DoD had 13 updates before it was completed and burried by newer games. In that time the market was smaller than today, so every update back then lasted longer on top of Latest Update, which means more visibility, but since the market was smaller it also mean less people here to Like the game.
Maybe this is the part I'm wrong, and correct me if that's the case, but MP is on v0.14 which means 14 updates (if the version number works in the same way that DoD does), which means less time at the top of Latest Update for visility in each update thanks to the bigger market, but also with way more people to Like the game thanks to the bigger market. Since MP had good graphics, it's easy for the game to shine on this market full of v0.1 low effort games.
So, MP had more updates already, better graphics, full animations, and even if people here say that they hate sandbox, according to most polls in General Discussion, sandbox is still people's favorite. Still MP has less Likes than DoD. It isn't like MP being the 27th most liked game here is a bad or shameful thing either, only god knows how many devs would kill to be in top 50. It's just that DoD was 19th before the DE and now it's 17th.
