Also Super Robot Wars T for $49.95 (+ Delivery) as well.
These are technically the "Asian" version of the games, with Japanese voice and Chinese + English subtitle options, so you'll have to set up a region specific accounts if you wish to buy any DLCs.
For those who are not so familiar with the series, the Super Robot Wars games are tactical RPGs that features crossover of wide ranges of mecha anime series (from mainstays like Gundam, to more old school and niche series, and sometimes series that barely even qualify as mecha), that weaves together their settings and events into an original story for each game… Though sometimes less weaving together, and more excuse plot handwaving.
You can refer to these pages below, to see what series are featured in each:
Each game has its own completely independent story, so you don't need to play any other games in the series to jump straight in, and you can play them in whichever order you like if you get them both.
This is the cheapest I've personally seen for physical copies of these games. In the past, even during "sales", they've been something like AUD $70+ each at online stores such as Play-Asia.
EDIT:
Super Robot Wars X trailer.
Super Robot Wars T trailer.
Have a casual interest in the Super Robot genre and I'm keen to give the games a go. Are the games collectibles?
