Is it a hyuna kinda voice ? <| sep |> Well the other guy isn ' t lol <| sep |> Simple really Most of the work was already done . DOTA 2 is an improved version of DOTA 1 , the latter of which was really getting on in years . For a brief time , DOTA 2 was also updated at the same time as DOTA 1 , albeit all function and improvements have been focused on DOTA 2 since then . Building on this , DOTA 2 was originally in the source engine IMO a fantastic engine followed by Source 2 , which Valve has been working on for years . League on the other hand is built in Papa Gespacho ' s Pizzaria from spaghetti and homegrown tomatos . In addition , most of the balance work and more is done by Icefrog . The madman basically handles everything himself and it shows , as DOTA is his baby . So , overall , Valve didn ' t actually have to do much work except when it came to the meat of the game . As another note The last few major games handled by Valve were all either games they didn ' t make themselves or mods they ' ve taken for their own . CSGO , DOTA 2 , TF 2 , Portal I believe was done by another studio before being grabbed , etc They don ' t really make these games so much as package them for the market and give it a coat of paint . Albeit CSGO and TF 2 likely have their own pretty violent gripes about Valve . Conversely , Riot had to build everything from scratch and tried to compare heroes at a cursory glance . Hence why many of the original League heroes are very similar to their DOTA counterparts Juggernaut vs . Yi , for example . From there , as Riot got bigger , they went from indie to major overnight . Their company infrastructure was and perhaps still is awful . They pushed content out to appease the playerbase instead of slowing content down to work on important things . Riot is the better version of Hello Games They ' re what happens when you give about 30 guys in a basement the keys to the city and tell them to make things bigger . One last thing League has seen improvements , albeit we don ' t remember them because of the negatives . Largescale map update . Far more model and champion updates comparative to DOTA 2 . Albeit you can swing that argument either way Additions in crafting and rotating game mode . And about fiveish new characters a year . We just tend to not remember them because the havenots stand out more than the haves . There are a few things to pick out but TLDRValve is an experienced company approaching a game where a majority of the work Design , Balance , Mechanics , etc was done , they just needed to polish it . Riot iswas a new company holding lightning in a bottle that they tried their hardest to keep up with . See Hello Games , Niantic for less successful stories .
