whitepuzzleIf ESEA dropped TF2 because it was losing them money, and ESL owns ESEA, for what purpose would ESL want to branch into TF2?
The reason why ESEA dropped TF2 wasn't because they were losing money; Premium Fees + League Fees likely gave them a slight profit with TF2. ESEA dropped TF2 because the game's league wasn't growing and because "TF2 only comprised of 1% of ESEA's population and the resources put into the game could be instead put into CS:GO and thus impact a greater number of people." Essentially ESEA sought to centralise its resources into CS:GO and TF2's low rate of return just made the game a tumour that ESEA put off cutting.
ESL Play, in comparison, is much broader and much more open in its catalogue of games, which includes over 25 at the moment. It's much easier for ESL Play to branch into TF2 because its backend is more flexible and because their structure is more oriented towards different games rather than just CS:GO and CS:GO alone.
