Unless you count +R and want to level up with players who don’t get exposed by Toronto. /profoundcockiness
Seriously though, I get what you’re saying and you’re right, depending which game we’re talking about. Someone playing a weeaboo poverty game, or any small game in general, is only going to have something to contribute to the Ottawa scene as a whole if that someone is finding a way to work themselves up to higher-level fighting game play with it.
I’ve screwed around with playing multiple games, and I’d argue that the transferable skills that you develop juggling games are only really worth it on three levels: 1) execution, 2) strategy, and 3) meta-learning. The thing about execution and strategy is that they’ll still only get you so far when you switch games. They only really become difference-makers with games that relate and share something in common. There are, however, fighting games out there that will never directly benefit from your years of practising crisp wavedashing or understanding when to pop burst.
What you really play a second game for is to capitalize on any potential enthusiasm and inspiration you have locked away, IF that’s what it’s going to take to motivate you to develop further than the last game you played. If the key to pushing yourself to train harder and drop time/money on actually travelling comes from playing that second game, go all into it. You’ll learn about how you learn and how you overcome hurdles in the process, which are the real universally transferable skills you want to develop as soon as possible in fighting games, imo. The more players that understand this, the more upper-end potential a local scene will have at its fingertips.
The thing is that you have to have enough motivation to deliver yourself to a high-level playing-field, and, the smaller the game’s scene, the further from home you’ll likely have to travel, the more effort you’ll have to put in alone, etc… etc…
Most people are simply better off focusing on one game, and maintaining their motivation-level via their own willpower. If the game comes with regular exposure to a community that’s good at motivating them—maybe through heated rivalries (the old-school American way), or maybe by pressure to give their peers the most “real” contribution possible (the over-idealized Japanese way)—even better. If the game comes with seven-figure prize pools and world-wide recognition… uh, wait, why aren’t you playing MOBA’s right now?
