I miss the days when the robots like Getter Robo or Commbattler V could split up into their smaller vehicles either for additional mobility, or when Dancouga could split into individual robots for combats, to increase chances of winning. Also, full transformations were really fun. But recent works, robots like Daiturn 3 and Cybuster can no longer transform, yet Z Gundam still can. Even Macross Valkyries can no longer transform to Gerwalk mode. Having the ability to have Gundams breaking up into their core fighters or armors were also good tactics in order to avoid enemy kills. And yes, the difficulty is no longer a big issue. In the past, beam weapons was D against water so if your enemy is hiding in the sea, your beam rifle attacks only scratched 10hp onto your enemies. Also, robots which cannot fly, can't even attack enemies in the air if they have no long range weapons. Only a terrain adaptor could fix this issue. Now, who equips terrain adaptors anymore??? Lol. Getter Robo was actually very relevant in those days for switching forms to adapt the land, air and sea combats. I rather they revitalize Alpha. Alpha is still the best for me.
Zoids was in the mobile Super Robot Wars game before, if I am not wrong. These days even non robots like Ultraman's son and Gridman are also involved. Even Godzilla was in the mobile game. The word "Robot" now holds no real meaning anymore.
